Trefasser's farms, houses and cottages are the only settled area of Pen Caer.[5]David Tress has painted the place in an abstract painting.
History
Trefasser was mentioned in the survey of episcopal lands in 1326.[5] It at one time belonged to Major Thomas Askwith Jenkins (1809–1877) of Trevigin.[6]
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.[7]
Etymology
There are opposing views as to from whom the name derives. One possibility is that it is the namesake of Bishop Asser, a friend and biographer of King Alfred in the 9th century. Another possibility is that it is named for Asser's nephew, Asser Meneventsis, as Trefasser is said to be his birthplace. Meneventsis was a Benedictine monk, as well as scribe and chancellor to Asser.[3][6][8][9]
Castell Poeth
A tumulus named Castell Poeth ("the Hot Castle") is located nearby. It is an exploratory castelet with an occasional beacon.[10] Described as a ditched, raised enclosure, oval in shape, and measuring 30 m (98 ft) by 60 m (200 ft) across, it has an attached second oval measuring 46 m (151 ft) by 54 m (177 ft).[11]
