The church, located at the head of Bishopston Valley, is dedicated to St Teilo who gives the village its Welsh name.

Two further names are recorded: Porthdulon (or Porthtulon), possibly referring to the area of Caswell, and Llancyngur Trosgardi.

Caswell Bay is a popular local beach due to its facilities and accessibility by car and seasonal bus services.

Other Bishopston beaches, such as Pwlldu Bay and Brandy Cove, which can only be visited on foot, see fewer visitors.

A group of local teenagers has campaigned since 2018 for a pump track to be built in the area, with Mansel Green having been chosen as the preferred site.
