Carlisle's flagship museum covers 2000 years of the city's past. The Roman Frontier Gallery explores Carlisle's Roman foundations, while the Border Galleries explore the city's past, from prehistoric settlers through to the Vikings and Border Reivers. There are some fascinating artefacts on display, including finds from the Cumwhitton Viking cemetery, which revealed a haul of helmets, swords and grave goods. The top-floor Lookout has cracking views of the castle.
A separate part inside Old Tullie House displays decorative art, sculpture and porcelain.
