St Madoc's Church
A number of prehistoric remains exist in the parish.
In 1833 Haroldston West had a population of 155. Its name is taken from that of an Anglo-Norman who held local lands.
In 1872 the population was 149, living in 28 houses in an area of 1,718 acres.
The parish church is dedicated to St Madoc of Ferns. Before the 1880s the church was a "barn-like old church of nave and chancel with big sash windows and a makeshift roof of salvaged ships' timbers" but had become derelict. It was rebuilt in 1885.
