Momin Mosque (Bengali: মমিন মসজিদ, Arabic: مسجد مؤمن‎) is located in Akon-bari, in the village of Burirchar, Mathbaria Upazila, under the district of Pirojpur in Bangladesh. The mosque is made of wood and structured without nails by woodworkers and calligraphers. The woodworks are arranged in geometric balance and painted with natural colors. A philanthropist in the village of Burirchar, Momin Uddin Akon, started building this mosque in 1913 by employing twenty-one artisans, and it took seven years to complete the work. In 2003, the Department of Archaeology (Bangladesh) recognized it as a national heritage and listed it under the name Momin Mosque for its care and protection. In 2008, the archaeological department started some restoration work on Momin Mosque; however, the restoration work somewhat changed its original appearance.
