JAISALMER

Page 2: Jaisalmer- secular architecture

Jaisalmer nicknamed "The Golden city", is a town in the Indian state of Rajasthan. It is located 575 kilometers (357 mi) west from the state capital Jaipur.

It was once known as Jaisalmer state. The town stands on a ridge of yellowish sandstone, crowned by a fort, which contains the palace and several ornate Jain temples.

Many of the houses and temples are finely sculptured. It lies in the heart of the Thar Desert (great Indian desert).

The majority of the inhabitants of Jaisalmer are Bhati Rajputs, named for Bhati, who was renowned as a warrior. This area was part of Gurjar - Pratihara empire and until the 11th century was ruled by a powerful Rajput Bargujar King. Deoraj, a famous prince of the Bhati family, is esteemed the real founder of the Jaisalmer dynasty, and with him the title of rawal commenced.

In 1156 Rawal Jaisal, The sixth in succession from Deoraj, founded the fort and city of Jaisalmer, and made it his capital as he moved from his former capital at Lodhruva (which is situated about 15 km to the north-west of Jaisalmer). In 1293, the Bhattis so enraged the emperor Ala-ud-din Khilji that his army captured and sacked the fort and city of Jaisalmer, so that for some time it was quite deserted. In Nankana Sahib, the Bhatti Clan can be traced from the lineage of Rai Bhoe and Rai Bular Bhatti.

The Jaisalmer princes had now arrived at the height of their power, but from this time till the accession of Rawal Mulraj in 1762 the fortunes of the state rapidly declined, and most of its outlying provinces were lost. In 1818 Mulraj entered into political relations with the British. Maharawal Salivahan, born in 1887, succeeded to the chiefship in 1891.

It is in this context that Jaisal Singh founded his fort on one of the hilly outcrops of the Aravalli range, called "Trikut“ because of its triangular plan. One major reason for selection of this site was the availability of sub-surface water. The fort was built on the hilltop, generally following its triangulargeometry. For various socio-cultural reasons , the town plan of Jaisalmer developed in the form of "padas"based on clan or profession and this division persists till today.

During the years 1750 to 1850 A.D. additions to thetown included fortifications around the town and theconstruction of many beautiful residential buildings called"Havelis". The most famous of these are Nathmaiji's haveli,Salim Singh's haveli.

House Form

Depending upon the socio-economic status of the inhabitant,there are “three types” of houses in Jaisalmer.

The simplest town house consists of a single room, a verandah anda courtyard. Larger houses of this type have anotherverandah over the entrance and some houses have anadditional room on one side of the courtyard.

A two or three-storey structure, this housetype can be considered the typical houses. It is similar to the first house type in plan, the only difference that additional rooms and small enclosed terraces are located at the upper floors. The front part of the first floor has a balcony projecting onto the street.

In these four or five-storied houses, the courtyard is surrounded by rooms or verandahs on all sides.There are underground rooms as well. The uppermost storey comprisesterraces enclosed by wind pavillions and high parapet walls. In some cases, the house is built around two courtyards.

The common building material used in Jaisalmer is stone ofWhich,

Light yellowish sandstone is usedfor walls, which are 0.45m or more in thickness. In betterquality construction the stone is dressed and joints madeaccurately without any mortar.

The individual stones are held together by stone keys cut into the blocks themselves or by iron cramps.

In houses the stone is undressed and the walls are built in mud mortar and finished with mud plaster.

At upper floor level, where the building facadeprojects out, 50mm thick panels of limestone are used as wall elements.

These are deeply carved in various geometricalpatterns and from outside the building they give theappearance of latticework (jali).

In Jaisalmer, the layout of the town is the first defence againstthe harsh climate. Even though the major streets are notparticularly narrow, the street orientation of WNW-ESEensures that the building facades are either shaded by thebalcony and sunshade projections (for high solar altitude andsouth facing facades) or by the buildings opposite.

Considering (for simplicity) an E-W street orientation, insummer the sun would be shining on the south facade from9.30am to 2.30pm. The corresponding solar altitudes duringthis time are 54° to 86° and even small horizontal projectionsare sufficient to shade the south-facing building .

The north face of the building receives solar radiation before 8 am and after 4pm with solar altitude being less than 35°. At this time the building opposite shades the northern facade even if the street is relatively wide.

An interesting feature of Jaisalmer is the use of texture. Thishappens at three different levels of organisation.

At the town scale, the buildings are of unequal heights with wind pavilions and high parapet walls creating an uneven skyline and shading each other in the process.

At the second level, the building facades have a large number of projections like sunshades and balconies .

At the smallest level,the flat parts of the building facades are deeply carved creating finned surfaces. Such uneven structures andsurfaces can be considered extended surfaces.
