The present-day fort consists of a defensive structure and two main palaces, Gujari Mahal and Man Mandir, built by Man Singh Tomar (reigned 1486–1516 CE). The Gujari Mahal palace was built for Queen Mrignayani. It is now an archaeological museum. The second oldest record of ""zero"" in the world was found in a small temple (the stone inscription has the oldest record of the numeric zero symbol having a place value as in the modern decimal notation), which is located on the way to the top. The inscription is around 1500 years old.
