Pálvölgyi & Szemlőhegyi are two caves in Budapest, Hungary. To see the entire album (just nine photos), click here.
Confession: These photos are from a long time ago (November 2006) and some inconsistencies in my notes make me fear I might be mixing the two up with each other, and I was unable to resolve this through research.
Update: I just realized how perfectly the scenery aligns in the top two photos, making it seem like they’re part of the same panorama. They’re not; they’re two separate photos and it’s just a neat coincidence.
