Sakhi Sarwar , is a town in Dera Ghazi Khan District, Pakistan. It is named after a Muslim Sufi saint Syed Ahmad Sultan, also known as Sakhi Sarwar, whose tomb is situated in the vicinity.
The tomb itself was built in the 13th century in a small village named Muqam in the Sulaiman Mountains, 35 kilometres (22 mi) from Dera Ghazi Khan city. It was later expanded by the Mughal king Zahir-ud-din Muhammad Babur. It is a unique building of Mughal architecture.
An urs, or festival in the honour of Syed Ahmad Sultan, also locally called "Sangh Mela", has been celebrated for centuries during Vaisakhi (March–April), with thousands of pilgrims coming to the town from the nearby localities. Historically, followers of Syed Ahmad Sultan belonged to various religions – Max Arthur Macauliffe, a colonial office appointed in Punjab, observed in 1875 that not only Muslims but Hindus also visited the shrines during the urs.
Salt lakes form when the water flowing into the lake, containing salt or minerals, cannot leave because the lake is endorheic (terminal). The water then evaporates, leaving behind any dissolved salts and thus increasing its salinity, making a salt lake an excellent place for salt production. High salinity will also lead to a unique flora and fauna in the lake in question; sometimes, in fact, the result may be an absence or near absence of life near the salt lake.
