Perched on high ground overlooking the River Osento, Lacedonia grew up around a Lombard stronghold. Lacedonia first appears in recorded history in the early years of the 11th century (in the Chronicle of Lione Ostiense).
Over the succeeding centuries, ownership of the castle passed from hand to hand - Baldassarre Pappacoda (1501), Zenobia Doria (1584) and Andrea III Doria Panfili (1769), the last landlord of Lacedonia. Built in the early years of the 11th century, rebuilt during the Norman period and transformed into a noble residence in the early years of the 15th century, the Lombard stronghold was completely destroyed by an earthquake in 1456. Ferdinand I of Aragon was soon faced with a baronial revolt in favour of Renè of Anjou, the pretender to the throne. He overcame the rebellion in 1464. Over the succeeding years, his rule was threatened by another baronial revolt (1485-87). Ferdinand I of Aragon finally suppressed the barons by a series of arrests, trials and executions. At that time Lacedonia's Cathedral became famous for being the place where the rebellious barons gathered to plot against Ferdinand I of Aragon.
The Castle we see today was built by the landlord Baldassarre Pappacoda in 1508.
In 1930 the castle was damaged by an earthquake, and another followed 50 years later. Basically, Lacedonia castle consists of a round tower built mainly of limestone rubble. The tower has narrow windows with gun ports for defence. The curtain wall surrounded and protected the interior courtyard of the castle.
