The land type of Brussels is mountain land type, the road is sloped, many places are to climb stairs, such as here. This art mountain is not a mountain, but the slope is still a bit. It is easy to go down the stairs all the way, and it is not so easy to climb up all the way back. It feels like climbing the sixth floor. The accessibility facilities in Europe are much worse than Australia and New Zealand. There are elevators in Australia and New Zealand where there are basically stairs.
