Mughal Emperor Shah Jahan’s greatest contribution to Islamic architecture may be the Taj Mahal, but the Jama Masjid in Old Delhi isn’t too shabby either. Commissioned by the ruler and completed in the 1650s it can house more than 25,000 worshippers and is India’s largest mosque.
Appropriate dress is also required. Men should not wear shorts. Women should wear clothing that covers their shoulders and knees.
Jama Masjid is open to non-Muslims seven days a week in the mornings, 8:30 a.m. (earlier in the summer) until 12:15 p.m. It reopens at 1:45 p.m. and closes 30 minutes before sunset. If you plan to take photographs be prepared to pay a fee, about 100-150 rupees.
