Located on the slopes of the Civita Falconara hill, the Castle, whose oldest parts date back to the 13th century, takes its name from the king of Naples, Ladislao I (1376-1414) of the Durazzo d'Angiò dynasty, who here, according to ancient sources , moved his court for a while.
In the following centuries, the abandoned Castle suffered destruction and reconstruction, until from the 18th century and throughout the 19th century it became one of the largest wool mills in Arpino owned by the Ciccodicola family. With the industrial crisis, in the twentieth century, the Castle became the seat of an Institute for orphans of workers, then a military hospital and finally the Industrial Technical Institute for Chemists until 1985, the year in which the Provincial Administration of Frosinone, after the purchase, starts the recovery work to make it the exhibition site of the Donation and a congress center, with the aim of cultural and tourist enhancement.
