The kooky Filangieri Museum houses everything from Asian and European armour to ancient pottery and sumptuous paintings spanning the 15th to the 19th centuries. Much of the collection belonged to 19th-century prince Gaetano Filangieri, whose private, walnut-panelled biblioteca (library) afforded him commanding views of the newly restored Sala Agata (Agatha Hall). The hall is home to much of the collection, while the ground floor is frequently used for cultural events, including classical-music concerts.
Among the collection highlights are Luca della Robbia's delicate sculpture Testa di fanciullo imberbe (Head of a Beardless Boy), Adriaen Hendriex van Ostade's humourous painting Interno di taverna (Inside a Tavern), and Giuseppe de Ribera's deeply psychological canvas Santa Maria Egiziaca (St Mary of Egypt).
The palazzo itself dates back to the late 15th century, its design heavily influenced by the architecture of Renaissance Florence. Incredibly, the widening of Via Duomo in the 1880s saw the building demolished and reassembled 20m further back.
