Located within the boundaries of Trinant on its eastern border lies Llanerch-uchaf farmhouse, a grade IIlisted building. Of either late 18th century or early 19th century origin, the farmhouse and attached range have been noted for being examples of a 'regional farmstead retaining much of its historic character'. The farmhouse is a T-shaped two-storeyed build with the attached farm range of lime-washed stone rubble and Welsh slate roof. Horeb Chapel is another building of note in Trinant, completed in 1901. The current chapel is built on a plot of land 20 yards (18 m) from where the original Horeb Chapel stood in the 19th century.
