Belém (Portuguese pronunciation: [bɨˈlɐ̃ȷ̃]), whose name is derived from the Portuguese word for Bethlehem, is the southwesternmost civil parish of the municipality of Lisbon. Until 2012, the area of Belém had its own historic parish, named Santa Maria de Belém. In 2012, the Administrative Reform of Lisbon resulted in the merging of the latter and the parish of São Francisco Xavier, thus creating the new parish of Belém. Located at the mouth of the River Tagus, it is located 6 kilometres (3.7 mi) west of the city centre and 2 kilometres (1.2 mi) west of Ponte 25 de Abril (25th of April Bridge). Many of Portugal's distinctive buildings and landmarks are located in this area, including the Jerónimos Monastery and the Tower of Belém. The population in 2011 was 16,528, in an area of 10.43 km².
