Nationaal Scheepvaartmuseum Steen

This engaging museum houses model ships, maritime maps and instruments in the gatehouse and front section (which is all that remains) of the 13th-century castle, Steen. Highlights include an intriguing nautical totem shaped like a snake's head and boats from around the world, including an 18th-century coracle or skin boat. Beneath the next-door raised promenade is the museum's open-air collection of river barges, canal boats and De Schelde P905, a 1950's Belgian navy patrol ship.

It's on the foreshore of the River Scheldt to the immediate west of the old centre, within the partly-restored confines of a castle called the Steen that dates from 1200 and is Antwerp's oldest building.
