Tour du Guet, Medieval watchtower and lighthouse in Calais, France.
The Tour du Guet is a medieval fortification made of stone that rises about 39 meters above the central square of Calais. The structure contains multiple levels for observation and includes a section that was once used for raising pigeons.
The tower was built in the early 13th century under the rule of the Counts of Boulogne and served as a watch post for the town. A strong earthquake in the 16th century caused significant damage, prompting extensive repairs and reinforcements.
The tower shapes the appearance of Calais' central square and serves as a stone landmark that embodies the town's long past. Passersby immediately recognize its solid form and its role as a historical symbol of the place.
The structure is located in an active part of town and is easily reached on foot. Visitors should expect uneven stairs and tight spaces when exploring the different levels inside.
Inside the tower, traces of bird nesting areas are visible, showing how pigeons were used for sending messages in those times. This practical use for communication was unusual for medieval structures of this kind and can still be noticed today during a visit.
