About Tughalqabad fort
- Tughlaqabad fort is a ruined fort in Delhi, built by Ghiyasuddin Tughlaq, the founder of the Tughlaq dynasty.

Khirki Masjid at Jahanpanah: Khirki Masjid is a great example of Islamic architecture. It is a small quadrangle-shaped mosque and is covered entirely by a roof, which is an unusual thing for building of mosques. The presence of several domes on the roof along with the wonderful latticework or jali on the windows represents the typical Islamic style of architecture.
