It was heavily restored in 1841 and again in 1852. It has a large three-storied tower with a polygonal stair turret. Inside, the Peamore chapel has a plaster ceiling dated 1633, depicting the Twelve Apostles and the Four Evangelists, scenes of the Nativity, Christ carrying the cross and the Resurrection.

On a hill overlooking the Exe estuary at the north-west side of the village is the former Devon County Asylum (a "lunatic asylum") which was designed by Charles Fowler and opened in July 1845. It featured a central administration block with six radiating arms and had a capacity of around 800 beds. The hospital closed in the mid-1980s when it was known as Exminster Hospital. After years of neglect, the surrounding land was built upon for housing and the grade II listed hospital was converted to apartments and town houses; it is now known as Devington Park.
