The Twisted Monastery Fortress

Using one of the elements developed in the study of an impossible topographic
distortion, one can see that the fortress battlements can be observed
simultaneously from multiple perspectives: on both sides, they twist in a double-perspective.
The rear or top portion can be seen from a bird's-eye view, whereas
the front battlement plays tricks on the eyes and projects multiple perspectives
simultaneously.
