On one of the little hills that rise out of the river bank on the south there is a level platform on which are many carved gravestones like those on the Makli Hills at Thatta, which chain ornament and panels of Arabic quotations from the Holy Quran. The whole space between the graves is paved and a flight of steps leads up to the platform from the South side. Enameled tiled work is freely used on these tombs, most of which are dated 1018 to 1301 AH., that is between 1609 and 1883 AD. The principal grave is that of Mir Kasim one of the Sabzwari Shahids dated 1018 AD. This was probably the grave that sanctified the place, and a lamp post and lamp are placed in front of it still, and it gives the name of Than Kasim Shah to the hill. But the name of which it is more generally known is the hill of the seven virgins from the building on the southern side called Satbhain, which consist of a row of shallow rooms connected externally with coloured tiles. These cells are said to have been occupied by seven virgins, who had taken a vow never to look upon the face of man. Sir Richard Burton, however, maintains that this derivation is wrong, ignorant people having perverted Sati-jo-Than or seat of the Satis (i.e. celibate women) in to something which means seven.
