The dock commissioned by Henry VII at Portsmouth in 1495 is identified as the oldest surviving early-modern European dry dock still in use. The structure's endurance links Tudor naval administration with the modern historic dockyard. HMS M33, a First World War monitor, now occupies the dock and makes its original function easy to visualize. Waterfront infrastructure can outlive successive generations of ships when its dimensions suit new purposes. Visitors can see an early dry dock still performing a recognisable version of its original role.
