700 year old Begumpur Masjid of Tughlaq period
Biggest masjid in Delhi.
बेगमपुर मस्जिद
Begumpur Mosque is like a twin to its counterpart at Jama Masjid, similar in size but completely opposite in its present state to the Old Delhi mosque which is still in use. Similar to the Khirki Mosque nearby in its architectural motifs, there’s a debate as to whether the mosque was built during Muhammad-bin-Tughlaq’s or his successor, Firoz Shah's reign, with evidence pointing more towards the latter as Juna Shah, Firoz Shah’s prime minister, had constructed many mosques with similar architectural motifs (Khirki masjid being one).
