St Ffinan's Church, Llanffinan

St Ffinan's Church, Llanffinan is a small 19th-century parish church built in the Romanesque revival style, in Anglesey, north Wales. There has been a church in this area, even if not on this precise location, since at least 1254, and 19th-century writers state that St Ffinan established the first church here in the 7th century. The church was rebuilt in 1841, reusing a 12th-century font and 18th-century memorials, as well as the cross at the eastern end of the roof.

The church is still used for worship by the Church in Wales, one of eight in a combined parish, and services are held weekly. It is a Grade II listed building, a national designation given to "buildings of special interest, which warrant every effort being made to preserve them", in particular because it is considered to be "a good essay in a simple Romanesque revival style". The church is at the end of a gravel track in the countryside of central Anglesey, about 2.5 kilometres (1.6 mi) from Llangefni, the county town. It is also on a footpath to Plas Penmynydd, once home to Owen Tudor, founder of the Tudor dynasty.
