Fortresse Holland sets dockyard, dock and harbour side by side

The Museumloods (museum shed), dry dock, visitor depot and fortress harbour together form a maritime route through the history of Hellevoetsluis.

Plan your visit ↗

The scale model gives an overview

Use the interactive model of the Rijkswerf (naval dockyard) to place buildings, water and workshops. Then compare one part with what is still visible outside.

Dry dock with a guide

A guided tour takes you through the passages of Droogdok Jan Blanken. Ask the guide how the dock was used. Check the time slot and follow the safety instructions.

The depot has its own rhythm

The free visitor depot at Industriehaven 8a opens only on Wednesday and Thursday. Treat it as a separate location, not as a continuation of the museum galleries.

Before you go

The Museumloods is open Wednesday–Sunday 11.00–17.00. Guided tours of the dry dock are listed at 11.00 and 14.00, but the page still refers to 2025 for these; confirm the time slot. The depot opens Wednesday and Thursday 10.00–15.00.
