Hellevoetsluis

Hellevoetsluis was developed from the seventeenth century as the naval base of the Admiralty of the Maze, and it was built for that purpose rather than grown into it: a fortified harbour with bastioned ramparts, an inner and outer basin, storehouses, a rope walk and, from 1806, a dry dock that is one of the oldest in the country and still in place. From this harbour on 1 November 1688 William III sailed with a fleet of several hundred ships to England, landed at Torbay and took the throne in what became the Glorious Revolution - the largest amphibious operation launched from the Netherlands before the twentieth century. The old town inside the ramparts is small and intact, with the admiralty buildings, a lighthouse on the harbour wall and a naval museum. Historic ships lie in the basins and the ramparts are walked.

What you actually see

• A purpose-built naval base - bastioned harbour, storehouses and rope walk.
• An 1806 dry dock - among the oldest in the country, still in place.
• Where the 1688 fleet sailed - William III's expedition to England left from here.
• Historic ships in the basins - moored inside the old naval harbour.

When to go

April to October. A day.

Honest expectations

The museum and dry dock keep seasonal hours and close on Mondays. The town outside the ramparts is modern and unremarkable. Public transport from Rotterdam is slow.
