Gurio Lamanna
Gurio Lamanna (also incorrectly called Gurlamanna) is a doline shaped like a coat of arms located in the Murge plateau and falling into Gravina in Puglia's territory, on the border with Altamura, Apulia, southern Italy. It is "one of the largest karst landforms of the Murge plateau" and it is located very close to other two dolines, namely Pulicchio di Gravina and Tre Paduli.
