This map is very nice indeed. I have a couple of small queries with it. Firstly, I can't see the gate that Emma's Gate refers to - I can't see a feature in any of the surrounding walls that suggests the location of a gate. That might just be me being blind. Secondly, the map labels on the buildings and on the darker regions of the gravel areas are pretty tricky to read. Perhaps slightly heavier text for these (again, could be my eyes )

Other than these small points, this is a very clear map. It's great to see such a careful diagram of a real world fortress. It highlights many useful featuers of fortress design in a gunpowder era.
