Burg Rheinstein possesses a working drawbridge and portcullis, which are typical of medieval castle architecture and defences.

Between the rock and chapel, additional steps lead down to the royal crypt of Prince Frederick William Louis's family.

Heading upwards to the Burgundy Garden, another set of steps lead to the main part of the castle.

Known as the Rittersaal or Knight's Hall, it includes beautiful stained glass windows, as well as three-dimensional paintings.

Rheinstein houses a cafe and gift shop offering miniature handmade wooden treasure chests, as well as traditional items including postcards and guidebooks for purchase.
