A rampart is a long embankment or wall used as a defensive boundary. It protects a castle, hillfort, or settlement from attackers. These structures are usually broad on top. They are often made from excavated earth or masonry, which is stone or brickwork.

Ramparts are vital to military architecture because they define the perimeter of a fortified site. They provide a platform for defenders to stand and fight.

The way a rampart is built depends on the materials available. Simple designs are known as dump ramparts, which use mounds of earth and stone. More complex versions include box ramparts or timberlaced ramparts that use wood for strength. In Central Europe, builders used a style called a Pfostenschlitzmauer, or "post-slot wall." This design combines earth, stone, and timber posts.

Some stone ramparts were vitrified, meaning the stone was fired to make it stronger.

Early fortifications often used a combination of earth ramparts and external ditches. Builders would dig a ditch and use that soil to build the rampart. This made the barrier much harder to climb.

This method was common in hillforts and ringforts. In the early medieval period, this was a key feature of motte and bailey castles. These castles used earthworks to create high mounds and protective banks.

During the classical era, fortifications became more sophisticated. Societies began building tall ramparts made of stone or brick. These walls included a platform or wall walk for defenders. They also featured a parapet, which is a low wall to protect soldiers from incoming missiles.

Famous examples of these stone ramparts include Hadrian's Wall and the Walls of Constantinople. After the fall of the Western Roman Empire, many people returned to using earthwork ramparts.

Medieval ramparts became very detailed as castle technology evolved. A parapet often featured crenellation, which are rectangular gaps at intervals. The gaps are called embrasures or crenels, while the high parts are called merlons. Defenders could also use a loophole, or arrowslit, to shoot through narrow openings.

A chemin de ronde, or wallwalk, provided a pathway for communication and fighting. Some walls had machicolations, which are overhanging projections with holes in the floor. These allowed defenders to drop missiles or hot liquids on attackers below.

The invention of artillery changed ramparts forever. Solid masonry walls could break under the impact of heavy cannon shot. In response, engineers built thicker, lower ramparts. Some were built like Ravenscraig Castle in Scotland, which dates to 1460.

Builders began using earthen banks because earth could better withstand the impact of shot. These banks were often faced with stone or brick to keep them stable.

These new artillery fortifications used an angular design called bastions. Bastions allowed guns to create zones of interlocking fire. This system is known as the trace italienne because Italian engineers developed it. It was later perfected in northern Europe by engineers like Vauban and Van Coehoorn. This style remained the dominant form of fortification until the mid-19th century.

An artillery rampart included a terreplein, which is the top fighting platform. It also featured a banquette, a step that helped soldiers shoot over the parapet.

Archaeologists study ramparts to understand the history of military technology. These sites show how tactics and tools changed over hundreds of years. They also reveal local conditions from the time a fortress was built. For example, a rampart might contain a casemate, which is a vaulted chamber for storage or living. Or it might have a bartizan, a small turret for a sentry to watch from. Every part of the rampart tells a story about how people protected themselves.
