The tower has a ring of four bells. The oldest is the treble, cast in 1578 by Joseph Carter of Reading, Berkshire, who later became the master founder of Whitechapel Bell Foundry in London. The third bell was cast at Reading in about 1599. Robert II Wells of Aldbourne, Wiltshire cast the tenor bell in 1793 and he and James Wells cast the small Sanctus bell in about 1795. William Taylor cast the second bell in 1852, presumably at the foundry that the Taylor family then had in Oxford. Currently for technical reasons the bells are unringable.
