St. Fimbarrus has had a chequered history. Dedicated to St. Fimbarr, a sixth century saint, the original church was replaced by the Normans. Relatively little remains; the town was attacked by the French in the 1457 and the church destroyed. It was rebuilt in 1460. © Robin Pizzy.

Former Wesleyan Church, on Fore Street and Passage Street, now converted into flats. It dates from 1894. SX 126 518. © Andrew Ross.

This former chapel sits at the bottom of Lostwithiel Street. Can you give it a name? Now flats. SX 125 516. © Andrew Ross.

This one may not even be a former church, but one is marked on OS maps, and it is named St. Monica's. But as Andrew says, it doesn't look quite right for an old chapel. Can you supply any history? On Passage Street and Station Road. SX 127 520. © Andrew Ross. Rob Brettle has suggested that it may formerly have been the Salvation Army Hall.
