About the area

Haverfordwest facts

Haverfordwest is a built-up part of Swansea where housing, back lanes, walls and small pockets of open ground sit close together. It is part of the Haverfordwest, Tenby & the Pembrokeshire Coast area, within about 30 miles of Swansea.

  • Founded by Flemish settlers around 1110 with a Norman castle, it became Pembrokeshire's county town in 1543.
  • The town sits on the tidal Western Cleddau, crossed by the Old Bridge of 1726.
  • 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.

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 Haverfordwest.

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