The Old City Walls of Randgriz City are a 16th century fortification of the capital of the old Gallian Republic. They surround the Old City core of Randgriz City, which today serves as a portion of downtown. While the facade of the wall are still in place, the interior has been replaced with a modern concrete viaduct, which serves as the support for Randgriz City Metrorail Line 2. The wall itself forms a nine and a half mile long circumference around the city core. The Old City district inside of the wall is a historic district, with only a few exceptions allowed for modern development.
