The idgah at Agra, a 17th c (probably) Mughal structure, is a better architectural specimen than most idgahs in India, which are usually nothing more than a tall, long qibla wall with arched niches. This one is more like a large Mughal-style mosque with prayer hall, and is set at the end of a large walled garden.
