English: Khirki Masjid (meaning ‘windows’ or ‘brackets’) is one of the few mosques in the country which is covered for most parts. Lying as one of the mosques in the ancient city of Jahanpannah (connecting Tughlaqabad and Siri), it lies close to the Satpula gates, and was built by Firoz Shahs Tughlaq’s Prime Minister, Khan-i-Jahan Junaan Telangani.

Not only is the mosque built on a different beat than its counterparts of that era, but it also has a rare blend of Hindu and Islamic styles, built on a cross-axial platform with a tight geometry, almost like a mini fortress.

Instead of one big open courtyard, the mosque has four smaller square courtyards measuring thirty feet by thirty. Due to modern day construction all around, little sunlight is filtered in through the lattices in the upper floors. Another interesting design is the terrace. Partitioned into 25 squares of equal size, each square has 9 domes on each side, measuring 81 in all, and these square blocks are alternated by 12 flat roofs, giving a very distinct shadow upon the interiors. One can take the eastern flank stairs to reach the roof, and a visit is imperative to comprehend the mathematical beauty of its design.

Khirki Masjid is one of the most complex and elegant constructions of the Tughlaq era, which was otherwise more attuned towards simple and rugged constructions. It is said to be a precursor to the Lodi and Mughal styles that were to evolve later on. Although there is minimal decoration both inside and outside, the geometrical intricacy of design is a marvel in itself.
