  • The site has been fortified in some form since the early twelfth century.
  • Part of the City and County of Swansea, served by Swansea Council for waste, roads and public land.
  • Terraced and semi-detached housing, back lanes and boundary walls are typical of this part of the city.

Local habitat

Where to look

Back lanes, boundary walls, vacant plots and disturbed roadside ground are the main places where invasive or escaping garden plants can establish around Castle.

This is habitat guidance, not a claim that a particular property or site is infested.
