Château de Cinq-Mars-la-Pile

Château de Cinq-Mars-la-Pile is a fortress in France with two round towers from the 12th and 13th centuries. These towers are connected by wide moats that were rebuilt during the 16th century, showing how the defensive structure evolved over time.

The fortress began as a medieval structure and underwent modifications during the Renaissance, particularly in the 16th century. In 1642, Cardinal Richelieu ordered its destruction after the execution of Henri de Ruzé d'Effiat, a favorite of King Louis XIII.

The fortress displays typical medieval military design with its round towers and guard house that served as the central control point. Visitors can climb the stone spiral staircases within the towers and understand how defenders once operated the structure.

The site is partially accessible, but visitors should expect uneven paths and steep stairs within the towers. Comfortable footwear is recommended, and it is best to check current opening times before visiting to avoid disappointment.

A triangular structure called the Eperon extends from the southeast side of the site and terminates in a bartizan positioned strategically at its tip. This unusual shape was an innovative defensive approach, allowing defenders to watch approaching attackers from multiple angles.
