Wheelchair ramp?

This seemingly suicidal wheelchair ramp is in the Rand Gallery mall near where I live. There is no way anyone could get a wheelchair either up or down this steep set of steps and besides, the footpaths and streets are so wheelchair unfriendly,  a person in a wheelchair could never even get to the mall. Come to think of it I have only seen one person in a wheelchair and he was a gypsy begging so it was unlikely that he even needed a wheelchair.

The bucket is to catch leaks when it rains. All buildings here have flat roofs and most are poorly constructed  - it is a rare building that doesn't leak. In this instance the ceiling has crumbled and great chunks are missing.
