The "Stedelijk Museum" in Amsterdam is an international museum dedicated to modern and contemporary art and design. It has been closed for renovations for 10! years but in 2012 it was reopend at last and the whole interior is new. I had mentioned it before in a post in 2012 here.
The museum has many different stairs and even a huge escalator.
The old museum has been expanded with a new extension ( called the bathtub), with the stairs in the pictures above, but this one is in the old part.
