Visiting the castle is quite easy. Its slope is practicable but only on foot. When Count Ugoline fell into misfortune, Siliqua and the castle fell under Pisans' control. From 1324, the castle and the surrounding area were occupied by the Aragonese and, after belonging to different families, they were eventually included in the Barony of Monastir and in the Marquisate of Villacidro. In 1785 they were redeemed by Vittorio Amedeo, King of Sardinia.
Siliqua still conserves its typical, beautiful churches. St.George's church, opposite Mount Granitico's building, was built in the XIV Century in the gothic-Catalan style and preserves a beautiful wooden crucifix dated back to the XVIII Century.
Two other churches deserve to be mentioned: St. Anne's church, contemporary to the previous, and St. Sebastian's church.
Among the most interesting events are the celebrations in honour of St. George, martyr and Siliqua's patron (end of April), St. James the Apostle's feast (3rd Sunday of May), St. Joseph Calasanzio's feast (last Sunday of August) and St. Margaret from Antiochia's feast, celebrated in the homonymous, rural church with traditional food tasting.
