Tower with ramp or external staircase

[MarcoP]

The tower is located in Asia. I can't read the word within it, but given the religious focus of the map I guess it could represent Jerusalem?

Thank you, Koen, beautiful map!
The red pilcrows before the most important labels in the map are not frequent, in my opinion. Interesting.

The tower seems to be labeled "Jerl'm", which confirms your interpretation.
