The Royal Naval Base, Devonport

Devonport is the largest Naval Base in Western Europe and clustered tightly around it are the streets that originally housed its thousands of workers. It still covers over 650 acres and has 15 dry docks, four miles of waterfront along the River Tamar, 25 tidal berths and 5 basins. Take a look at this interactive panorama of the dockyard Alongside its surface ship refitting facilities, Devonport is the only site in the UK equipped to conduct nuclear submarine refits.

But the importance of the Dockyard to employment and the economic prosperity of Plymouth has diminished over the years.  However, it is estimated that the base generates about 10% of the income for the city and creates business opportunities for 400 local firms.
