Taipa is an area in Macau, connected to Coloane through the area known as Cotai, which is largely built from reclaimed land. Located on the northern half of the island, Taipa’s population is mostly suburban. Administratively, the boundaries of the traditional civil parish Freguesia de Nossa Senhora do Carmo are mostly coterminous with that of the former Taipa Island, except for a portion of the parish that lies on the island of Hengqin (Montanha), housing the campus of the University of Macau.
