Visitors enter the church through the existing tower into a barrel vaulted nave. At the centre is a dome, supported on four Ionic columns, which is lit by a lantern above. The barrel vault extends into the aisles from the dome in a Greek-cross form, leaving four flat ceilings in the corners of the church. The church is well lit by plain glass windows in the aisles and originally there was a large east window in the chancel, that is now covered by a reredos. The plasterwork ceiling is finely decorated, and the barrel vaults are lit by elliptical windows.
