The semi-desert region of Shekhawati, lying in the triangular region between Delhi, Jaipur and Bikaner, is famous for its plethora of painted havelis (mansions), all commendable pieces of the rich artistic traditions of this region. Starting around the 14th century, a number of Muslim clans' move into the area and the towns, which developed in the region, became important trading posts on the caravan routes emanating from the posts of Gujarat. The 'Open Air Gallery of Rajasthan', as it is popularly called 'Shekhawati', the Land of Shekhs, derives its name from Rao Shekha (1433-88), one of the descendents of the Kachhwaha family of Jaipur, who was one of the first to establish his clan here. Although the towns have long since lost any importance, they may once have had, what they have not lost is the beautifully painted havelis (mansions) constructed by the merchants of the area. Most of the havelis ate from the 18th century. The region also has forts, a couple of castles, baolis (step wells), chhatris (cenotaphs) and mosques.
