In a rural situation near Matthew Arnold’s ‘stripling Thames’ between Bablock Hythe and Newbridge, the church is an almost unaltered example of the Decorated style of the early 14th century, with two wide transepts and much good window tracery. The 17th-century Laudian altar rails are of unusual quality and were given to St John’s College, the patrons of St Denys’ Church, by Archbishop Laud.
