A short distance from Pembroke, Pembroke Dock was built on a grid of wide roads with the focus on its naval dockyard. Operating over more than 100 years, the dockyard produced 260 fine ships. During the Second World War, Pembroke Dock became home to the Sunderland Flying Boat base. Today the town is renowned as the gateway to Ireland, with daily sailings to Rosslare.

On the surface, the town is simply a useful shopping centre, but an interested observer will find clues to the town's illustrious history everywhere. A heritage centre is housed in the Martello Gun Tower, near the Dockyard wall.

Explorations in any direction may lead to unexpected pleasures - smart waterfront areas, picnic sites and parks included. Before the Cleddau Bridge was built, small ferries carried vehicles from bank to bank. The hamlets which grew up around these tiny ports still exist, each with its own inn, providing an interesting perspective on the waterway.
