In the early 1990s, I had the privilege of discovering and getting to know the "Aichelburg Ruins," as it was then called. The medieval castle was completely overgrown, and it was very difficult to find a way to the walls. The interior had collapsed and was also overgrown. It's wonderful that the ruins have been brought back to life and now bear the name "Aichelberg Castle Ruins." They deserve the distinction of being "absolutely worth seeing."
