I’ve been to the Denver Art Museum a couple of times now and still the main staircase is a little disorienting. The sides of the stairway are not perpendicular to the direction of the steps themselves; they angle to the right. So if you start on the right hand side of the stairway and go straight up the stairs, you are continually getting farther and farther away from the handrail. Or if you hang onto the handrail as you go up, you are climbing the steps at an angle. Strange, and the angles of the upper floor openings just add to the disorienting feeling.
