Heritage Open Day: St Martin's is a medieval church with an impressive 14th century roof, wall paintings and a Norman tower damaged in the 1648 Siege of Colchester. The chancel roof so impressed the leading church architect Sir Gilbert Scott on a visit in 1876 that he paid for its restoration. The wall paintings are a small part of a Doom painting of the early 16th century; figures from Hell on the south side, with demons tormenting the damned, and the saved on the north side. There is an exceptionally fine stained glass window of the six miracles of Christ by the firm of Heaton, Butler and Bayne, 1865.
