Jama Masjid in Agra is opposite the Agra Fort and overlooking the Agra Fort Railway Station. The Jama Masjid is also popularly known as the Jami Masjid or "Friday Mosque". It is one of the larger mosques in India. The Mosque was built by Shah Jahan in 1648 and dedicated to his favourite daughter, Jahanara Begum. There was a spacious, octagonal Tripolia Chowk which existed between the Jama Masjid and the Delhi gate of the Agra Fort. This Tropolia was destroyed in order to create the Agra Fort Railway Station. The cloisters have engrailed arches supported on pillars.
The main entrance is through the eastern side. The prayer chamber has a façade with a broad arched iwan in its centre and is adorned with slender turrets alternated with kiosks. Its dome is the largest and highest of the three domes crowning the sanctuary. All the bulbous domes have inverted lotus and kalash finials on the top and have narrow zigzag courses of white marble alternated by broad bands of red stone. There is a fountain with four kiosks in its corners in the centre of the courtyard. The interiors of the western wall have a beautiful mihrab and pulpit in white marble. The Persian inscription in white marble inlaid with black stone on the archway of the central portal is in praise of Jahanara and Shah Jehan.
The pristine beauty of the mosque must have been awesome as indicated by its comparison with Baitul-Mamur, the fabulous mosque of rubies and pearls situated in the fourth sky. It is said that once surrounded by a market place called Tripolia set in an octagonal (Muthamman) Chowk that was built between the Delhi Gate and the Jami Masjid. But, it was later destroyed in 1871-73 to acquire space for laying down the railway tracks for the city. It required six years and 5,000 workers to finish.It was made by using red sandstone and marble.
