- The Tower Museum contains two permanent exhibitions and hosts a number of touring exhibitions throughout the year. The "Story of Derry" exhibition outlines the city's history from its earliest fomation to the present day. The "An Armada Shipwreck, La Trinidad Valencera" exhibition tells the story of the Spanish’s Armada ship, La Trinidad Valencera's journey around the Irish coast. It was shipwrecked off the coast of Donegal in 1588 and discovered in 1971. Both exhibitions use a range of display and interactive techniques to present their stories. These projects total almost £3 million and have received major funding from the Heritage Lottery Fund, Northern Ireland Tourist Board and Derry City Council.
