The castle
In the exterior shots it is a completely different castle from the one featured in the 1958 film, anyone can see that.
But the interiors are the same in both films. The thing that makes a bit of confusion is that in some of the rooms the orientation changes. For example, here the staircase leading up to the upper floor stands on the right hand-side of the hall and then the corridor runs towards the left. In the 1958 film it is the other way round. I wonder if the director did it this way deliberately in order to confuse the audience or it was just a goof as a result of the eight-year gap between the making of the two films? But in this case they should have watched the first film before starting to shoot the second so there would be not spatial discrepancies.
What is your opinion, fellows?
