The stronghold that put both the 'new' and 'castle' into Newcastle has been largely swallowed up by the train station, leaving only a few remaining fragments including the square Norman keep and the Black Gate, both fresh from a £1.67-million restoration. Exhibits inside the two buildings cover the history of the city, its castle and its residents from Roman times onwards. The 360-degree city views from the keep's rooftop are the best in town.
