Trinity House, Edinburgh

Trinity House is a Georgian building with an unusually practical past. It served Leith’s mariners as a guild hall, customs house, and base for maritime administration and poor relief. In earlier centuries, the same institution also provided an almshouse and hospital.

Its lower vaulted structures come from an earlier building, while the present house was designed by Thomas Brown and completed in 1818. The organisation taught navigation, licensed pilots, and helped maintain lights around the Forth and Scotland’s coast. Today, the building is in state care and houses a maritime museum.

Its collection includes a portrait of Mary, Queen of Scots, once identified as Mary of Guise. The building’s story is therefore not only about shipping: it connects seafaring with education, welfare, navigation, and the care of mariners.
