Castello Chiaramonte, Medieval castle in Palma di Montechiaro, Italy.

Castello Chiaramonte is a medieval fortress built on a rocky cliff above the Mediterranean Sea near Palma di Montechiaro. It features defensive towers, thick stone walls, and a chapel with original architectural elements from the time it was constructed.

Federico III Chiaramonte ordered the castle built in 1353 on a rocky spur above the sea, and its position made it important in the fight against pirates. After Andrea Chiaramonte's death and the confiscation of his estates, it passed to the Moncada, who renamed it Montechiaro to erase the memory of the previous lords. It later went to the Caro and, in the 17th century through a female line, to the Tomasi; Carlo Tomasi Caro received the title Duke of Palma from Philip IV of Spain, took monastic vows and ceded his goods to his brother Giulio, second Duke of Palma and first Prince of Lampedusa.

The castle chapel holds a Madonna statue that the scholar Caputo attributes to Antonello Gagini; the attribution is debated, not certain. A local legend says inhabitants of Agrigento stole the statue and the people of Palma recovered it after a fierce fight, which gave the nearby stream the name "vallone della battaglia".

The castle stands on a rocky spur above the sea at Marina di Palma, a hamlet of Palma di Montechiaro. The site has long been abandoned and later restored with questionable work, so the brick-framed windows and modern terracotta floors are visible signs of those interventions. Access to the interior is not described in the sources; check locally before planning a visit.

A local legend says the chapel's Madonna statue was stolen by people from Agrigento and brought back by Palma's residents after a long fight; a stream nearby is still called the "vallone della battaglia" (valley of the battle). The Caputo attributes the statue to Antonello Gagini.
