O'Doherty Tower stands in the center of the city of Derry, in County Londonderry, in Northern Ireland. As O'Doherty Tower inhabits a museum it is also known as the Tower Museum.
Although O'Doherty Tower may look historical, it is not. It was built in the early 1990's during a campaign to refurbish the historical center of the city. It was built in the north corner within the city walls, next to the Magazine Gate, in the style of an Irish tower house. It was built to commemorate an original 17th century O'Doherty Tower. This original tower has now disappeared and would have stood more to the west, near the Castle Gate.
O'Doherty Tower can be visited as a visitor of the Tower Museum, which houses exhibitions about local history and the Spanish Armada. When I came by the museum was closed. Too bad, I would have liked to take a look from its top floor over the walled city. A walk over the city walls is also recommended.
