Gurio Lamanna is a broad karst depression in the countryside outside Gravina in Puglia, a landscape feature rather than a built monument. Its scale is the attraction: a sudden natural hollow in limestone country, with scrub, fields, and big skies around it.
It is best for travellers who like geology, walking, and quiet rural detours. Combine it with Gravina's ravine and cave churches to get a fuller sense of how water and limestone have shaped this part of inland Puglia.
