What is a "curtain tower"?

A curtain tower is a defensive tower built into or alongside the curtain wall of a castle or fortification. The curtain wall is the outer wall that surrounds the fortress, and the curtain tower adds strength and height to this structure. Typically taller than the surrounding wall, a curtain tower provides an elevated position for defenders to observe the area and engage attackers. These towers often have openings for archers or cannons, allowing for effective defense from multiple angles. Curtain towers are an essential part of medieval military architecture, enhancing both the security and visual impact of the fortification.
