Within
the Hauz-Khas Enclave
lies this rubble-built but plastered mosque, survived now only by its
prayer-chamber, pierced by three arched openings and surmounted by a
single dome over the central portion.
Above the chhajja, its façade is ornamented with blue tiles, which
have given it its present name, meaning the 'blue mosque'. Over its
central archway is an inscription, from which we learn that it was built
in 911 AH (1505-06) during the reign of Sikandar Lodi, by Kasumbhil, nurse
of Fath Khan, son of Khan-i-Azam Masnad 'Ali Khawas Khan, then governor of
Delhi.
