Rampart (fortification)

A rampart is a long bank of earth or a wall. It forms a protective boundary for a castle or a settlement.

These structures help keep people safe inside a fortified site. Some ramparts are simple mounds of earth and stone. These are called dump ramparts.

Other designs are more complex. They might use timber or stone to stay strong. Some use a special style called a post-slot wall. This uses earth, stone, and timber posts together.

Many early ramparts worked with a deep ditch. People dug the ditch in front of the bank. This made the wall much harder to climb.

In the early Middle Ages, people used earth ramparts for motte and bailey castles. As time passed, ramparts became taller and stronger. They were often built from stone or brick. These walls had a parapet to shelter the defenders. A parapet is a low wall on the very top. It protects people from missiles thrown by attackers. Defenders could also use a wallwalk to move around. This was a path behind the parapet for fighting.

History shows how ramparts changed as tools changed. In the classical era, societies built tall stone walls. Famous examples include Hadrian's Wall and the Walls of Constantinople. After the Western Roman Empire fell, people went back to using earthworks. This lasted until the 11th century. Later, castle technology evolved during the Middle Ages. Walls became thick and had crenellations. These are the rectangular gaps in a wall. The high parts between the gaps are called merlons. Defenders could shoot through the gaps, called embrasures. They also used narrow openings called arrowslits to stay safe.

When big guns called artillery were invented, ramparts had to change. Solid stone walls could break under heavy shot.

New ramparts were built much thicker and lower. Some used earthen banks to soak up the impact. Builders often took the dirt from the ditch to make the bank. These new shapes used angular projections called bastions. Bastions let guns fire at attackers from many sides. This system is known as the trace italienne. Italian engineers led the way with this design. Later, engineers like Vauban and Van Coehoorn perfected it. This style was used until the mid-19th century.

Modern experts study these sites to learn about the past. Ramparts show how military technology and tactics grew over time. They also show how people lived in different places. A rampart might have a small turret called a bartizan. This gave a sentry a good view while staying safe. Inside the wall, there might be a vaulted chamber called a casemate. These rooms were used for storage or for sleeping. Some ramparts even had machicolations. These were openings in the floor to drop things on attackers. Every part of the wall had a specific job to do.
