Located on the Caribbean coast of Colombia, the Cartagena Walls were built in the 16th century as a Spanish colonial military defense against piracy and foreign invasion. The walls, which surround the old city for several kilometers, are made of solid stone and are well preserved, making them one of the most representative fortifications in Latin America. Today, it is not only a UNESCO World Heritage Site, but also a popular destination for tourists who want to enjoy the city and sea views, and experience the historical atmosphere, especially during a romantic stroll at dusk.
