Historically, it is part of the parish of Llanwnda. It lies on the coast of St George's Channel within the Pembrokeshire Coast National Park. A stream named Cledde Goch runs close by.
Trefasser's farms, houses and cottages are the only settled area of Pen Caer. David Tress has painted the place in an abstract painting.
History

Trefasser was mentioned in the survey of episcopal lands in 1326. It at one time belonged to Major Thomas Askwith Jenkins (1809–1877) of Trevigin.
In July 2009, the body of a 47-year-old man from Stourbridge in the West Midlands was found at the bottom of the cliffs of Trefasser.
Etymology
The general consensus is that Trefasser is named after Bishop Asser, a Welsh churchman who was friend and biographer of King Alfred in the 9th century and may have been his birthplace.

Castell Poeth
A tumulus named Castell Poeth ("the Hot Castle") is located nearby. It is an exploratory castelet with an occasional beacon. Described as a ditched, raised enclosure, oval in shape, and measuring 30 m by 60 m across, it has an attached second oval measuring 46 m by 54 m.
