The tomb of Shah Rukn-e-Alam was built by Ghias-ud-Din Tughlak during his governorship of Depalpur, between 1320 and 1324 AD.
Sheikh Rukn-ud-Din Abul Fath (1251–1335) commonly called Shah Rukne Alam was among the eminent Sufi saints from Multan, Pakistan.
His tomb is the focus of the pilgrimage of over 100,000 pilgrims from all over South Asia who visit and commemorate his memory.
The tomb is located on the southwest side of the Fort premises. This elegant building is an octagon. Besides its religious importance, the mausoleum is also of considerable archaeological value as its dome is reputed to be the second largest in the world.
The mausoleum is built entirely of red brick, bounded with beams of shisham wood. The whole of the exterior is elaborately ornamented with glazed tile panels, string-courses and battlements. Colors used are dark blue, azure, and white, contrasted with the deep red of the finely polished bricks.
