The highlight of an excursion through Merw is a visit to Sultan Sanjar’s mausoleum, the tall brick walls of which still dominate the landscape and functioned as a landmark for traveling caravans.

This central-cupola building without portal is typical of the Khorasan architectural style. The mausoleum was created by Mohamed, the son of Atsyz of Serakhs, whose name we can find on a medallion below the cupola of the mausoleum.
