Castello di San Giorgio Monferrato, Medieval castle in San Giorgio Monferrato, Italy

Castello di San Giorgio Monferrato is a stone fortress with multiple towers and crenellated walls that rise above the vineyards of Monferrato. The structure occupies a hilltop position and features interior spaces that have been adapted for modern use while retaining their historic character.

The castle dates from the 10th century and is one of the oldest fortresses in the area still standing. In the 13th century Guglielmo VI of Montferrat granted the fief to the Avogadro family, and the last Palaeologus, Giovanni Giorgio del Monferrato, built its thick walls. In 1533 Montferrat passed to the Gonzaga of Mantua; French troops occupied the castle repeatedly and the Spanish partly destroyed it in the early 17th century. Ferdinando Carlo Gonzaga-Nevers then ceded it to the Gozani family, who rebuilt it and held it until the early 20th century.

The castle hosted the tribunal of the Inquisition and was for centuries the seat of noble families, first invested as a fief in the 13th century by Guglielmo VI of Monferrato in favour of the Avogadro. Its name comes from the village of San Giorgio Monferrato, which grew around the fortress on the hill. The former guest quarters now house a hotel-restaurant with a wellness centre.

The castle offers overnight stays with several rooms and serves regional breakfast. Visitors should be prepared for steps and uneven historic floors in certain areas.

The walls display different construction techniques from various periods, visible in the stone patterns and masonry joints. These layers reveal repairs and modifications the fortress underwent over the centuries.
