Museo della Speleologia e del Sottosuolo

The Museum of Speleology and the Underground is one of the civic museums housed in Nardò’s Castello Acquaviva d’Aragona. Its subject—the region’s caves and underground landscape—belongs to the karst terrain that shapes the city’s territory and nearby coast.

Why it matters

The museum places the underground within Nardò’s wider cultural landscape. The municipality identifies karst formations, including the flooded sinkholes known locally as spunnulate, as defining features of the area. The museum’s focus on speleology connects this geology with the caves and subterranean spaces of the Salento.

What to notice

The castle setting brings the museum into a civic collection that also includes the city museum, a collection devoted to peasant life and traditions, an exhibition dedicated to poet Vittorio Bodini, and a botanical garden. Together these institutions place natural history, local culture and the history of the town in the same complex.

Context and history

The Castello Acquaviva d’Aragona began as a fifteenth-century fortress and was later transformed into a noble residence. The municipality now uses the complex for civic and cultural purposes. In this setting, a museum devoted to speleology draws attention to the geological character of the Nardò area and to the role of caves in the landscape of the Salento.
