It is located between the northeastern end of the main island and St. David's Island. Originally called Southampton Port, it was renamed as a result of its heavy fortification in the early decades of the Seventeenth century. A gem of Bermuda's coastline, it is surrounded by St. George's Parish in the north, east, south (Tucker's Town), and Hamilton Parish in the west.
