201 Dome Mosque, Religious complex in Gopalpur, Bangladesh

The 201 Dome Mosque is a prayer hall in Tangail District, Bangladesh, known for its many vaulted roofs. The central dome rises over 80 feet into the air, while the remaining 200 smaller vaults each measure around 17 feet and form a repeating pattern across the entire roof.

Construction began in January 2013 on 15 bighas of land on the east bank of the Jhenai River in South Pathalia village, Gopalpur Upazila, Tangail District. The Heroic Freedom Fighter Mohammad Rafiqul Islam Welfare Trust initiated the project, whose foundation stone was laid by Rizia Khatun, mother of the trust's founder chairman. The estimated cost is BDT 100 crore, and the mosque remains under construction.

The mosque's name comes from its 201 domes: one central dome of 81 feet surrounded by 200 smaller domes of 17 feet each. The western wall is covered with tiles bearing the entire Qur'an. The main door is to be made using 50 maunds (about 1,848 kg) of brass, a detail visitors can look for as construction proceeds.

The building stands about 7 kilometers from the center of Gopalpur and can hold up to 15,000 worshippers during prayer times. Visitors to the grounds will find facilities for medical care and housing for elderly people alongside the main prayer hall.

The 137-metre minaret stands southwest of the prayer hall, not at its centre, and is described as the tallest concrete minaret in the world. The complex also has a helipad, and the western wall carries the entire Qur'an in tilework.
