Piccolomini Castle, Medieval castle in Capestrano, Italy.

Piccolomini Castle in Capestrano consists of two L-shaped buildings completed in 1485 on the site of a medieval fort whose prismatic tower still stands in the inner courtyard. The main facade, facing the town square, is flanked by two round towers and carries the Piccolomini coat of arms above the entrance, with five Renaissance marble windows on the first floor. The castle now houses the municipal offices.

The fortress was completed in 1485 and replaced an earlier fortification on the site. It was then modified by several noble families including Acquaviva, Piccolomini, and Medici who shaped its appearance and layout.

The inner courtyard centres on a 15th-century marble well flanked by two columns with carved capitals. Stone stairways lead from the courtyard to the upper floors, and the old medieval tower closes the north-east side. The name in use comes from the Piccolomini family, one of several noble households that held the castle.

The castle now houses Capestrano's municipal offices, so the main L-shaped wing and its courtyard are best seen on weekdays. The original east entrance, with its ravelin and the chain holes of the former drawbridge, faces the old moat side and is reached by a stone stairway.

The entrance was originally on the east side, protected by a moat; the ravelin and the chain holes for the drawbridge survive, and the drawbridge itself has been replaced by a stone staircase. The Piccolomini coat of arms above the main entrance marks the family that gave the castle its name.
