Devonport, in Devon, was formerly called Plymouth Dock. It is now a district of Plymouth, although it was at one time the more important settlement. Devonport was originally one of the "Three Towns" (along with Plymouth and East Stonehouse) which were merged in 1914 to form what would later become, in 1928, the City of Plymouth. Devonport was first incorporated as a municipal borough in 1837 under the Municipal Corporations Act 1835. It further became a county borough under the Local Government Act 1888.

Tavistock is a market town on the River Tavy, from which its name derives. It traces its history back at least to AD 961, when Tavistock Abbey, whose ruins lie in the centre of the town, was founded. Its most famous son is the sailor, privateer and circumnavigator Sir Francis Drake.
