The largest mosque in India, Jama Masjid rivals the grandeur of the neighbouring Red Fort in its scale and beauty. With two 40 metre-high minarets on either side, onion-shaped marble domes, and an aesthetic use of white marble and red sandstone, it is easily one of the prettiest Mughal-era mosques in India. Built in the 17th century, the mosque can hold approximately 25,000 people. There’s nothing quite as magnificent as the sight of flocks of pigeons flying around its massive central courtyard. For a bird’s eye view of the surrounding area, climb up the southern minaret (unescorted women are not allowed).
