public. In 1960, the Stapferhaus Lenzburg cultural foundation was established and moved into the Hintere Haus. Between 1978 and 1986, the castle was once more thoroughly renovated, and a French-style garden established in the southwest section. In 1987, the canton transferred its comprehensive cultural history collections to the castle and opened the Historisches Museum Aargau (Historical Museum of the Aargau), which in 2007 became the Museum Aargau (Aargau Museum). Since 2009, the displays have been undergoing renovation in stages.

Inside the middle gatehouse (which was also built in 1625 and enlarged in 1761–62), the path makes a 180° turn and leads up to the drawbridge and through the inner gatehouse into the inner bailey. On the east side, the inner bailey is protected and has 7 buildings arranged in a horseshoe. On the southwest side, the French-style garden is enclosed within the curtain wall. While the ground is fairly level within the walls of the castle, outside it falls off rapidly.
