We visited the citadel last year and found out aftewards that there is a large bat roost that might be visited. As we are keen wildlife enthusiasts this is something we would be keen to see and might even give our world mammal lists a boost as flying bats are rather hard to identify. I've seen conflicting information about accessibility. Our most likely dates for visiting will be 30th and 31st December and 2nd January. Does anyone know if this will be possible on ay of those dates?
