Heritage Open Day: Medieval parish church with 15th century Doom painting. Although there has been a Holy Trinity on this site since 1113, the current building dates mainly from the 14th century. It is one of Coventry's three churches with tall spires, and has survived the Reformation, the Civil War and World War II. The Doom painting was created in the 1430s, and is considered one of the best examples in Britain; its excellent state of preservation may be due to being covered up for most of its history.
