I don't think the walls on this are at all correctly aligned with the castle itself.

Tons of missing streets here.

Is this a path or something here?

Parking

Does this footpath not link up with a road or anything?

This road doesn't seem to exist on the aerial map, and in fact goes through many buildings.

Is this part of the road accurate? It looks like you'd need to drive through houses to get to this point.

Is there actually a building here? In the satellite images there's a building, in the aerial there isn't.

building borders need improvement
