CHAPTER 1
INTRODUCTION
1.1 INTRODUCTION
India has a long history of architectural development which
contributed to numerous temples spread throughout the length and breadth of
the country. Religion was the motivating force behind the construction of
these numerous temples in India. The development of temple architecture in
India has two distinct styles classified as North Indian/Indo Aryan and South
Indian/Dravidian. Most of these temples were constructed out of stone and
promoted by the rulers themselves, on colossal scales. There were also other
temples smaller in scale built by local communities using locally available
materials.
North Indian temples were predominantly built out of sandstone
and South Indian temples were predominantly built out of granite. As a
peculiar case the earliest structural temples belonging to the Pallava reign in
South India were built with sandstone. The Pallava temples being over
1500 years old, have been subject to deterioration caused by environmental
agencies over a period of time. As these temples are the earliest ones in South
India, they laid the basis for a fully developed style (Ananthalwar and Rea
Alexander 1980). It is therefore necessary that these temples are protected,
conserved and preserved to enable their sustainability for future generations.
This doctoral work looks at conservation of sandstone temples built by
Pallava rulers from 674 A.D. – 800 A.D. at Kanchipuram located in the
northern region of the state of Tamilnadu.

1.2 AREA OF STUDY
1.2.1 The Geographical Area of Study
The area of the study is Kanchipuram town, Kanchipuram district,
Tamilnadu, India. Ancient Kanchipuram, the city of a thousand temples, is
one of the seven most sacred pilgrim centers in India. Kanchipuram was ruled
by the Pallavas and being the capital city, the Pallava rulers added glory to the
town as they embellished the city with gigantic temples and shrines. Though a
number of temples exist in Kanchipuram, the royal temples built by the
Pallava rulers are declared as protected monuments by the Archaeological
Survey of India (ASI) because of their historical and aesthetic value. These
temples are the focus of this study.
The Geographical location of the study is Kanchipuram town,
Kanchipuram district, Tamilnadu, India (Figures 1.1 to 1.4). Kanchipuram
district is situated on the north eastern coast of TamilNadu adjacent to the Bay
of Bengal. Kanchipuram is bounded in the west by Vellore and
Thiruvannamalai districts, in the north by Thiruvallur and Chennai districts, in
the south by Villuppuram district, and in the east by the Bay of Bengal. It lies
between 11° 00' to 12° 00' North latitudes and 77° 28' to 78° 50' East
longitudes. The district has a total geographical area of
4,43,210 hectares and a coastline of 57 Kms and Kanchipuram town is the
district headquarters. For administrative reasons, the district has been divided
into 8 taluks with 1214 revenue villages.
The general climate of Kanchipuram district is hot and semi arid.
The maximum temperature is 37.10°C and the minimum temperature is
20.5°C. The highest annual rainfall recorded is 1423 mm and the lowest
annual rainfall is 985 mm.

1.2.2 History of Kanchipuram
In ancient geography, Thondaimandalam was an ancient division
comprising roughly the present districts of Kanchipuram, Chennai, Tiruvallur,
Vellore and Tiruvannamalai. The capital of Thondaimandalam was the
present Kanchipuram town ruled by the Pallava Dynasty.
The city was called as Kachchipedu, Kachichi and Kanchi in the
past (Jouveau Dubreil 1918). Yuan Chwang, the great Chinese traveler, who
visited the city in the 7th century stated that this city was 6 miles in
circumference and that its people were famous for bravery and piety as well
as for their love of justice and veneration for learning. He further recorded
that Buddha had visited the place (Rea Alexander 1909). As regards learning,
Kanchi stood second in glory only to Banaras. The history of Kanchi can be
traced back to several centuries before the advent of the Christian era. The
place finds its name in Patanjali's Mahabhashya written in the second century
B.C. Manimekalai, the famous Tamil classic, and Perumpanattu Padai, a great
Tamil poetical work, vividly describes the city placing its origins at the
beginning of the Christian era.
From the 3rd
to the 9th
century A.D., Kanchi was the capital of the
Pallavas who ruled over the territory extending from the river Krishna in the
north to the river Kaveri in the south. The Pallavas fortified the city with
ramparts, moats, etc., with wide and well-laid out roads and fine temples.
They were a great maritime power with contacts with far-off China, Siam,
Fiji, etc., through their chief Port Mamallapuram, the modern Mahabalipuram.
Ancient Kanchipuram, the city of a thousand temples, is one of the
seven most sacred pilgrim centers for the Hindus, the others being Ayodya,
Mathura, Maya, Kasi, Kanchi, Avanthi, Duvaragai. Today, apart from its
6
temples, this small town is also known for its thriving handloom industry.
Kanchipuram town is also known as the Silk City since the main profession of
the people living in and around it, is weaving silk sarees. The silk weavers of
Kanchi settled there more than 400 years ago and have given it an enviable
reputation as the producer of the best silk sarees in the country.
1.2.3 Architectural Developments in Kanchipuram
Kanchipuram has been regarded as one of the holiest and most
important cities of Ancient India. The Pallavas embellished the city with
gigantic temples and shrines and also excavated many tanks and lakes. Of the
palaces, forts and residences built by them, there is little or no evidence
(Jouveau Dubreil 1918). Temples and other religious structures have
sustained over time due to religious worship and festivals. The religious
enthusiasm and devotion during the Pallava rule was manifested in the
magnitude of the temples and the highly sculpted temple forms.
1.2.4 History of Pallava Architecture
Four distinct periods of Pallava history are recognized (Table 1.1),
the earliest covering roughly two centuries, the 3rd
and 4th
century A.D, the
second period covering the 5th and 6
th century A.D, the third and fourth
periods together, extending from the latter part of the 6th century A.D down to
almost the end of the 9th century A.D. In the later half of the 9
th century the
kingdom fell to the Cholas who ruled Kanchipuram till the end of 10th century
A.D (Rea Alexander 1909).
The most important groups of Pallava monuments are situated in
and around Kanchipuram town. The architectural style under the Pallavas
7
corresponding to the 3rd
and 4th
period is classified as per the Table 1.1 and is
also linked with the kings who ruled the period.
Table 1.1 Architectural style of the Pallavas (Rea Alexander 1909)
Sl.
No. Period Style Duration
1 Early period Mahendra style 610-640 A.D
2 Intermediate period Mamalla style 640-674 A.D
3 Late period –First phase Rajasimha style 674-800 A.D
4 Late period – Second phase Nandivarma style 800-900 A.D
Under the Mahendra style, the rock-cut cave temples were
excavated from natural rock. These temples were very crude in form and
rudimentary in nature because, first, the style was in the initial stages of
evolution, and second, the craftsmen worked with granite which is difficult to
work on. The Mamalla style was little refined and took the form of free
standing, monolithic rock-cut temples known as ‘rathas’. These monuments
are situated in one of the World Heritage Sites of Tamilnadu, Mamallapuram,
and the Shore temple is a World Heritage Monument.
The late period – had two phases. In the first phase, structural
temples were built of sandstone. These monuments are situated in
Kanchipuram town and are the first structural temples of South India, with
great refinement in architectural style and intricate features. In the second
phase of the late period, the temples were made of composite materials. The
lower portions of the temples are built of sandstone and the upper portion i.e.
the tower of the temple is built of brick with lime plaster.
8
After the collapse of the Pallava kingdom around 900 A.D., temples
were built by their successors – the Chola kings in Kanchipuram. The
construction of these temples was slowly shifted from sandstone to granite
during the early Chola period, the reason probably being the durability of
granite. Monuments built after the early Chola period are made of granite or
brick with lime plaster (Srinivasan 1975). One these temples – Jwaraheswara
Temple, constructed out of granite in the early Chola period is under the
protection of the ASI.
1.2.5 Temples in Kanchipuram
The study undertaken by The Directorate of Census Operations,
Tamilnadu in 2002, reveals that Kanchipuram District has 2359 temples on
the whole, Kanchipuram Taluk has 347 temples and Kanchipuram town has
56 temples (Government of Tamilnadu, The Directorate of Census Operations
2003).
As part of the present study an inventory of sandstone temples in
Kanchipuram town was made and it is found that 25 temples are made of
sandstone. 11 temples are unprotected (the regular maintenance of the temples
and routine religious practice are taken care of by the Hindu Charitable and
Endowment Trust), six temples are taken care of by the State Departments of
Archaeology (SDA), Tamilnadu, and six temples are taken care of by the ASI
and declared as protected monuments. During the inventory of sandstone
temples in Kanchipuram town it was found that except the ASI monuments all
other temples had additions to the original temple in different styles and with
different materials.

1.2.6 History of Sandstone Monuments
Out of the six temples under the ASI, those of Kailasanatha,
Iravathaneswara, and Piravathaneswara were built by Narasimha Varman I
between 700 A.D - 728 A.D. Mukteswara, Matangeswara, and Vaikuntha
Perumal temples were built by Nandivarman II from 732 A.D - 796 A.D. Of
these temples the Kailasanatha and Vaikuntha Perumal temples are on a larger
scale.
All monuments are of the typical Pallava style-externally, a lofty
tower built over the central shrine rising, in tiers, diminishing in size as they
approach the summit; in front of this shrine is a large pillared hall or mandapa
approached through a small porch (Longhurst 1928). The Piravathaneswara
temple is an exception in that it has a pyramidal tower over a central shrine
without a porch or a pillared hall. A characteristic feature of these Pallava
temples is the typical pillar found in them. The base of the pillar is carved in
the shape of a conventional lion sitting in an erect position and carrying the
shaft of the column on top of its head (Longhurst 1928).
A granite slab was introduced at the plinth level of the monuments
to act as a structural tie as well as to prevent water seepage into the super
structure. This structural detail is typical for all sandstone monuments - royal
temples and community temples - built during the Pallava reign.
1.2.7 Conservation of Sandstone Monuments in Kanchipuram
The monuments in Kanchipuram town are taken care of by three
agencies, the ASI, the SDA, Tamilnadu, and the private trustees of
Kanchipuram town. From the point of view of conservation there is no data or
primary information available in order to conserve these monuments. As a
10
beginning in this direction this study concentrates on the Pallava sandstone
monuments protected under ASI.
The sandstone monuments taken care of by the ASI in
Kanchipuram town are shown in Figures 1.5 to 1.10.

1.3 MOTIVATION OF THE STUDY
1.3.1 Previous works on the area of study
The previous works on the conservation of sandstone monuments in
Kanchipuram are limited to the following:
History of the city of Kanchipuram, the history of the kings who
have built the monuments, their family details and the grants given to others
by the kings are valuable sources of the history of the monuments (Rea
Alexander 1909; Jouveau Dubreil 1918; Longhurst 1928; Meenakshi 1936;
Srinivasan 1964, 1971; Mahalingam 1967,1988; Srinivasan 1979).
Studies on the architectural styles of the monuments, photo-
documentation of the monuments, the general maintenance of the monuments,
annual cleaning, and minor repair works, landscaping the surroundings and
security of these monuments are taken care of by the ASI (Government of
India, ASI 1980).
Scaled drawings of these monuments and their status with respect
to their condition and deterioration over the years are not available.
1.3.2 Focus of the Study
During the field study it is found that the deterioration of the
monuments is primarily due to the extensive weathering of sandstone
surfaces. To cite a case, weathering has so altered the monuments that in
several places the surfaces of the octagonal columns are rounded off to a
circular form. A higher level of deterioration of sandstone is seen on the
14
external surfaces of the structure than on the internal surfaces as these
surfaces are exposed to external environmental forces.
Figures 1.11 to 1.16 illustrate the examples of weathering damage
seen on the monuments.

The primary data on the present status of the deterioration is not
available to carry out conservation work on these monuments. Besides, the
nature and characteristics of sandstone used have not been investigated, thus
hindering conservation work.
Authentic records on the source of sandstone procured for the
construction of the monuments are not available. At present ASI uses
sandstone blocks procured from ruined and collapsed temples and temple
tanks in Kanchipuram town for the restoration works. Once this resource is
depleted there will be a need to procure fresh sandstone. There are no
operational quarries existing in Tamilnadu for sandstone, since Tamilnadu is
basically a granitic region and granite is a prime building material for
construction. Hence the study attempts to fill the gaps on these aspects.

1.4 RESEARCH QUESTIONS
1. What are the characteristics of the sandstone used in the
monuments?
2. What is the extent of decay of sandstone used in the
monuments? Can the extent of decay of sandstone be
measured qualitatively / quantitatively and what
methodology should be adopted?
3. Where are the sources to obtain fresh sandstone for future
conservation works in the absence of operational sandstone
quarries in Tamilnadu?
4. Will the sandstone obtained from these sources be
compatible with the sandstone used in the monuments?
1.5 SCOPE OF THE STUDY
1. A study of the properties of sandstone used in the
monuments and the study is limited to geological aspects
and does not go into the engineering properties of sandstone
2. Investigation of the present status of deterioration of the
sandstone monuments
3. Exploration of possibilities to locate fresh sandstone
compatible to the sandstone used in the monuments.
1.6 OBJECTIVES OF THE STUDY
1. To characterize the sandstone used in the monuments
2. To investigate the present status of deterioration of
sandstone used in the monuments by decay mapping
18
3. To identify the geographical locations in Tamilnadu which
will provide geologically compatible fresh sandstone as
replacement material for future conservation works
