St Maughold's parish church is of 11th century origin, with 12th to 15th century modifications.  The building retains parts of a well-executed Irish Romanesque-style doorway, indicating its erection or rebuilding during that century. Foundations of a building with different orientation underlie the nave, showing that the 11th century church was not the first on the site. Parts of the walls are 12th century with some 13th and 14th century and possible 15th century remains.
