What is ramparts?

Ramparts are defensive structures that are used to fortify cities, towns, and military bases. They consist of a thick and high wall made of stone or brick, often with towers at regular intervals, and are designed to protect the people behind them from attackers or enemies. Ramparts usually have a walkway on the top of the wall, which is used for patrolling or to provide firing positions for archers or gunners. Some ramparts also have ditches or moats in front of them to make it more difficult for invaders to reach them. Ramparts have been used throughout history, from ancient times to the present day, and were particularly prevalent in medieval times. Some famous ramparts include the Great Wall of China, the walls of Constantinople, and the walls of the ancient city of Jericho.
