Corporation of Trinity House

The Corporation of Trinity House was incorporated by royal charter in 1514. There is a tradition which dates the existence of Trinity House from the thirteenth century but there is no firm evidence to support this. When the charter was granted, Trinity House had a hall and almshouses at Deptford. Premises were acquired in Ratcliff and Stepney in the seventeenth century and meetings were held at all three sites. The Corporation bought a property in Water Lane in the City of London in 1660 which they then used as their hall. The Hall at Water Lane twice burnt down and was rebuilt, in 1666 and 1714. When it proved too cramped for proposed improvements in the 1790s, the Corporation bought land at Tower Hill on which Trinity House was built 1793-6. The present building retains the 1790s facade but a bomb on 30 December 1940 destroyed most of the rest of the original building which was sympathetically rebuilt in 1952-3.

The Corporation of Trinity House has had three main functions for most of its history:
1) General Lighthouse Authority for England and Wales;
2) Principal Pilotage Authority for London and forty other districts;
3) Charitable organisation for the relief of mariners.
These three functions are described in more detail in the introductory notes to the lighthouse, pilotage and estates and charities records.

The Corporation of Trinity House has had many other functions, largely carried out by the Board of 10 Elder brethren. Elder brethren are elected (for life) from the pool of around 300 Younger brethren who are normally Merchant Navy captains, though a few Royal Navy officers are also admitted as Younger brothers. These other functions have included the supply of ballast to ships in the Thames; sitting in the Court of Admiralty to hear collision cases; examining Royal Naval navigation officers in pilotage; and the examination of Christ's Hospital mathematical scholars in navigation.
