The large church of St Nicholas was built in part for the garrison at nearby Grosmont Castle. It is a 13th century building with a very long chancel, striking nave and double piscina. A French architect is said to have designed it for Eleanor, the queen of Henry III. The central spire rises from an eight-sided tower. Inside is an effigy, thought to be Henry of Grosmont, Duke of Lancaster who died in 1361. The church was partly rebuilt in the 19th century using a medieval design.
