Before long, the corporation was responsible for the licensing of mariners and pilots and for 'keeping the sea lanes' between
Whitby and
Berwick-upon-Tweed. At the same time, the corporation was (and had been since its early years) active in charitable work, including the provision of almshouses for aged mariners and the establishment of a school on its premises. The corporation was a high profile organisation in the city, for example hosting a visit by
Archduke Frederick of Austria in 1841, and presenting him with a commemorative gold snuff box. All these activities were financed principally through the levying of duties on every ship entering the Tyne to trade – a practice which only ceased in 1861. Following the passing of the Harbour and Passing Tolls Act in that year, the corporation began to devolve some responsibilities to other bodies; in particular, a new board took on responsibility for pilotage on the Tyne, and a new commission took on maintenance of the river's channels and buoyage, together with the corporation's lights at North and South Shields. Newcastle Trinity House continued though to be responsible for
buoys, marks and lights along parts of the coast until the mid-1990s. In the latter part of the 20th century the corporation's Trinity Maritime Museum occupied a pair of early Victorian warehouses on Broad Chare, adjacent to the main site. The museum closed in 2002 and the buildings are now leased by the
Live Theatre Company. ==Present-day activities and governance==
