Sarai Amanat Khan was built by Persian calligrapher Amaanat Khan, who is also credited with inscribing verses from the Koran on the Taj Mahal. Two gateways, Lahori Darwaza and Dilli Darwaza, flank a large open courtyard that houses a mosque, a well and a makeshift stable. The most striking feature of this Mughal-era monument is the fantastic blue glazed tile-work that adorns its gates and mosque.
