Ambleside Roman Fort is the modern name given to the remains of a fort of the Roman province of Britannia. The ruins have been tentatively identified as those of either Galava or Clanoventa, mentioned in the Antonine Itinerary. Dating to the 1st or 2nd century AD, its ruins are located on the northern shore of Windermere at Waterhead, near Ambleside, in the English county of Cumbria, within the boundaries of the Lake District National Park.
