Fortified cities of Belgium

Fortified cities of Belgium are historical urban centers equipped with extensive defensive structures like walls, ramparts, and fortresses built mainly between the 16th and 19th centuries. These fortifications aimed to protect cities from invasions and attacks during times of warfare. Notable examples include Brussels, which has medieval walls, and Liège, with its impressive citadel. Today, many of these structures are preserved as cultural heritage sites, offering insight into past military engineering and urban defense strategies while serving as tourist attractions and public spaces.
