Paloc - Kuća u kući

This quirky spot is exactly what it sounds like — a small house literally built inside the ruins of a much larger one, and it's been protected as a cultural monument because of how fascinatingly odd it is. You start with a short 6-minute video explaining the legend behind it, then get to walk through the tiny structure itself. The whole visit takes maybe 15 minutes, but it's one of those genuinely strange little detours you'll keep talking about.
