The Palace of Counts Pressio-Colonnese, today known as Eustachi Palace, dates back to the first half of the 17th century.
The noble building is characterised by a picturesque façade with a double arched upper loggia, which delimits the small garden courtyard in front of the building on two sides and is surrounded by walls on the other two sides.
Currently in great disrepair, inside the various rooms bear traces of deteriorated frescoes and decorations and grotesques.
Adjacent to the palace is the Church of St. Catherine.
