From the Chain Bridge, we walked up the stairs to the Castle. Feeling fit, we chose to walk around the funicular railway and climb the stairs near Clark Ádám tér and the Kilometre Zero marker. But as with everything on this trip, we find the stairs being repaired, and have to detour. This castle hill is now covered in a number of different stairs to the top, each with a particular historic aspect and view.

The castle is built on the top of a steep hill on the edge of the Danube where it has been protected by walls for more than 1000 years. The steepness of the hill itself would have at one time been protection from marauding tribes, but was walled to protect the monarch and the settlement that grew around the castle.

We walked around the ground and ramparts before inspecting the museum. This is an extensive museum, with exhibits of art, of history and culture. Of interest was information about the change of methods for providing water to the monarch and other inhabitants of castle and settlement through the years. Initially water was carried up the stairs in buckets by servants, and later pumped by horse driven wheels, allowing the castle to withstand long sieges.
