This compact town started as a troglodyte community, as a number of cave dwellings are open to view below the town.
Occupying the highest is the castle, firmly rooted to the rocky spur on which it resides.
Below the castle are two large caves that are now used as anthropological museums, previously they were used as stables.
Built on many levels, the castle at Sperlinga sits on a number of caves or grottos that were used themselves as stables, prison cells, and forges to make and maintain weaponry.
The castle is in good condition, and partially restored. During the time of our visit, it was undergoing continued reconstruction. There is a 4,000 lire entrance fee, and a public bathroom is available
