Bab Al Bahrain is a historical building located in the Customs Square in central business district of Manama. It marks the main entrance to the Manama Souq. Opened in 1949 and designed by the British adviser to the emir, Charles Belgrave, Bab Al Bahrain once stood on the Manama coastline. Due to extensive land reclamation in the later half of the 20th century, the structure is now several kilometres inland. The square is considered to be the region's first formal public space
