St Mary’s parish church was built there on the site of an earlier church in 1849. It was designed by diocesan architect Henry Kennedy (1814-1898). Kennedy was born in London and settled in Bangor after training as an architect. His career in church architecture was prolific and spanned some 50 years. The old parish church, which is a Grade II listed building, closed in 1999. The historic dedication to St Mary was then transferred to the nearby Christ Church. The latter, which is also a Grade II listed building, was built in 1864, the construction being funded by landowner John Platt(1817-1872) of Bryn y Neuadd Hall.
