Henry de Beaumont in 1107
[''Medieval Secular Monuments – The Early Castles from the Norman Conquest to 1217'', page 29.] as the ''
caput'' of the
lordship of Gower. The castle is now ruined and only two blocks remain, though the site has been improved in the 2010s for use as a public space.
Location
Swansea Castle is located on the east side of the city centre, facing Castle Square (the
River Tawe used to flow a short distance east on what is now the Strand).
Originally covering , the surviving remains of the square castle include residential blocks, together with a section of parapet wall forming an L-shape to the southeast. There are five tunnel-vaulted basement rooms.

The castle owners were subsequently absentee landlords. By 1650 the castle was described as "a decayed Buildinge".
By the 1670s the square tower was being used as a bottle factory and, in 1700, a town hall was built in the castle courtyard. By the mid 1700s the Great Hall had become Swansea's
