The Hull Trinity House, locally known as Trinity House, is a seafaring organization consisting of a charity for seafarers, a school, and a guild of mariners. The guild originated as a religious guild providing support and almshouses for the needy, and established a school for mariners in 1787. By the 18th century it had responsibilities including management of the harbour at Hull, and buoys and pilotage in the Humber estuary.
After the loss of many of its responsibilities as a result of the Humber Conservancy Act of 1852, the guild continued its work as a charity, and the provision of education, which continues to the present day.
The school, now known as Hull Trinity House Academy, is now a secondary boys' school.
The charity, Hull Trinity House Charity, supports seafarers and their families; supported by property holdings, it operates rest homes, as well as Welton Waters Adventure Centre.
The Trinity House was formally established in 1369, by the adoption of the 'first subscription deed', in which Robert Marshall (Alderman), and around fifty other people founded a guild, the Guild of the Holy Trinity, similar to other religious guilds of the day – it would have masses said, attended at the Holy Trinity Church, buy candles, attend funerals, and aid any sick member of the guild. The subscription fee was 2 shillings. Initially there was no clear connection with maritime trades.
In 1457,Edward IV granted the rights of and (duties payable for loading and unloading), enabling the guild to build an almshouse and chapel for thirteen persons impoverished by some misfortune relating to seafaring. It is thought by Sheahan 1864, p. 458 that the guild amalgamated with a 'Shipmans Guild' in around 1457. The same year the property known as "Trinity House" was acquired from Carmelite friars. (It was rebuilt 1753.)
In 1541 Henry VIII re-affirmed the guild's right to charge lowage and stowage for the support of an almshouse with a charter, as well as the rights of a legal entity, such as the ability to sue or hold property. The charter was re-affirmed in 1547, 1554, and 1567.
