Het Steen is a medieval waterfront fortress at Sint-Jansvliet 1, on the right bank of the River Scheldt in the old town of Antwerp, in Flanders, Belgium. It is the oldest surviving building in the city, with origins in the early 13th century, and was long the heart of Antwerp's defences before serving as a prison and later a museum.

Medieval waterfront fortress on the Scheldt, one of Antwerp's oldest buildings, with a riverside promenade.

Het Steen is a medieval waterfront fortress at Sint-Jansvliet 1, on the right bank of the River Scheldt in the old town of Antwerp, in Flanders, Belgium. It is the oldest surviving building in the city, with origins in the early 13th century, and was long the heart of Antwerp's defences before serving as a prison and later a museum. Its gatehouse features a stone relief of Semini, a bearded figure that locals describe as a giant, and a statue of Lange Wapper, a legendary shape-shifter of Antwerp folklore, stands at the entrance. The castle was heavily rebuilt in the 19th century, and the building has been used by the National Maritime Museum and later for exhibitions and events. Today the exterior and the surrounding promenade are open at any time, and visitors typically spend 20 to 30 minutes walking around the walls and the quay. The Scheldt riverfront here has benches, steps down to the water, a small beach-like terrace in summer, and good views of passing ships and the far bank. A short walk away is the Grote Markt with the Brabo fountain, and the Cathedral of Our Lady lies about ten minutes on foot. The best photo angles are from the promenade at sunset, when the stone glows and the river reflects the sky, and from the quay looking back at the gate with the Lange Wapper statue. Evenings are lively, with locals and visitors gathering along the quay, while early mornings are calm and ideal for photography. Interior access varies depending on events, so visitors planning to go inside should check the city tourism website beforehand. The cobbled paving can be uneven, and the riverside edge has drops, so care is needed with children.
