Heritage Open Day: Holy Trinity is the oldest standing building in Colchester, predating the Norman castle by three-quarters of a century. The tower of Holy Trinity was built by the Anglo-Saxons around 1000 AD and features a small west doorway and considerable quantities of recycled Roman bricks. Later additions to the church include the 14th-century chancel and Victorian extensions. It is the burial place of several famous people including William Gilberd (1544-1603), a pioneering Elizabethan scientist, and John Wilbye (1574-1638), a composer of madrigals or love songs. In the churchyard is the grave of the Battle of Trafalgar veteran Capt. Thomas Pinto RN (1774-1852), who, as a lieutenant, served aboard HMS Agamemnon. The church closed in 1953 and has had a variety of uses since. It is currently not open to the public. Only the churchyard will be accessible this year and a local guide will be on hand to describe the building.
