The original design featured a single entrance gate to protect residents from pirate raids.
The central square, known as the Plateia, houses the remains of the original Venetian keep.
Many of the houses within the walls were built using repurposed materials from ancient sites on the nearby island of Despotiko.
The settlement is organized around a 'donjon' concept, where the outer walls of the houses formed the primary fortification line.
The Venetian influence is evident in the heraldic plaques that were once embedded in the masonry of the houses.
The layout follows a concentric design, which was a specific defensive strategy used by the Venetians in the Aegean islands.
The Castle of Antiparos, or Kastro, is a 15th-century Venetian fortified settlement located in the heart of Antiparos town. Unlike typical defensive towers, it was designed as an enclosed residential complex consisting of a circular central courtyard surrounded by two-story dwellings. The fortification was commissioned by the Loredan family of Venice, who held the island as a fiefdom during the Middle Ages. Its unique architectural layout features a central tower (donjon) and rows of houses serving as the perimeter wall. Over centuries, the structure evolved to include small dwellings and chapels, many of which remain private residences today. The structure is built from local stone and reflects the Cycladic adaptation of the medieval Venetian 'kastro' model.
