Medieval Castle Parts –*Keep

One of the most important parts of the medieval castle was the Castle Keep. Historically the keep was the castle, other parts such as the curtain walls and towers were added to protect the castle keep and this is what we now picture as the castle. There is no doubt therefore that the castle keep is the main and most important part of the castle.

The keep was a stronghold that usually housed the king, lord and his family, all the important people and services were usually found within the castle keep.

Medieval Castle Parts –*Moats

Moats were of supreme importance in the defence of a medieval castle. A medieval castle moat was basically a deep and wide ditch that surrounded the castle and served as reliable protection against enemy assaults. A castle moat provided by a natural source was commonly much wider and deeper than a man-made moat.

Man-made castle moats were commonly around 12 feet wide and 30 feet deep but could have been wider and deeper.

Man Made Castle Moat Medieval Castle Parts

Man-Made Castle Moat

Castle moats were usually filled with water which was one of the reasons why most castles were built near a water source such as a river or a stream. Often castles were built on an Island or the edge of a lake or stream.

Medieval Castle Parts *Ramparts

Castle ramparts were commonly composed of a bank of earth and stone called ‘earthwork’ which served as a defensive structure upon which a castles walls were built.

A small wall called a parapet was commonly built on top of a castles walls, this was then crenelated giving it a toothed appearance and creating a battlement area where soldiers could defend the castle from.

Medieval Castle Parts *Walls

Medieval castle walls were central to a castle’s defence, the width and type varied from castle to castle. It was common to build medieval castle walls of widths ranging from 8 feet to 20 feet. Castle walls were joined by large towers that served a defensive purpose.

At the top of the medieval castle walls were crenellated battlements from which to defend the castle from besieging armies. There were also machicolations often added to a castles walls that created easier and more effective ways to throw stones and boiling liquids on besieging armies.

Medieval Castle Parts *Turrets

Another important component of a medieval castle was the turret.

Small Castle Turret - Medieval Castle Parts

A turret was a small tower that was constructed at the edge of a medieval castle wall. Its main purpose, like most other components of medieval castle parts, was defence.


Turrets were usually square-shaped but during the late medieval times, circular-shaped turrets became more popular because they provided a better line of sight for the archers defending the castle.

Medieval Castle Parts *Towers

In the defence of a medieval castle, towers played a central role. The main difference between a medieval castle tower and a medieval castle turret was that the turret was constructed on the wall at the top, whilst the castle towers were built from the ground up and part of the main structure.

Towers were mainly built of stone and included battlements and arrow loops for defence.

Medieval Castle Parts *Watchtowers *Look Outs

Both medieval castle turrets and towers also served the purpose of a lookout watching for the invading armies. A constant watch was maintained on the towers and turrets to keep an eye on any approaching armies or anyone else. It was common to build at least one turret at the highest wall which served as the primary lookout point.

Medieval Castle Parts *Drawbridge

The drawbridge was an important medieval castle part which was a movable bridge at the entrance of a castle above the moat. Since the medieval castles were defended by the moats, it was common to quickly raise the drawbridge in the event of an attack.

A Drawbridge could be raised by  a system of ropes, pulleys and or chains. Sometimes simple manpower was used to raise them.

Later drawbridges used a counterweight system.

Medieval Castle Parts *Barbican

A medieval castle barbican was a kind of fortified outpost that acted as the outer defence point for the castle often ahead of the castle main gatehouse.


Medieval castle barbicans began to be constructed after the Norman Conquest of England in 1066 and continued to be very important until the 15th century, after which they gradually lost their importance due to considerable improvements in castle siege tactics.

Medieval Castle Parts – Battlements

The medieval castle battlements were of central importance in the defence of a castle.

Castle Battlements

Battlements were commonly built around castle walls and on top of important towers.  The tooth effect of battlements were specially designed so that soldiers could fire bolts, arrows and throw stones or pour burning hot liquids at besieging armies.

Medieval Castle Parts *Murder Holes

Medieval Castles entrances were often protected by gatehouses, holes were built into the floors of higher level chambers above the gatehouses. Enemy soldiers were often tricked and trapped within the gatehouses spaces and corridors. These holes were called murder holes as the enemy below stood little chance of survival as boiling liquids and stones were poured and dropped on them from the defending soldiers above.

Medieval Cities and Towns often had gatehouses protecting them with murder holes incorporated in this way.

Medieval Castle Parts *Round Towers

Building round towers instead of square towers became popular during the high and late medieval periods. The obvious advantage of a round tower over the square tower was that it provided a clear line of sight for the archers, thus making the defence of the castle easier.

Another feature of primary importance was that, unlike the square-shaped towers, round towers were relatively immune to tunneling under the tower due to the absence of any corners required for tunneling.

Medieval Castle Parts *Arrow Slits *Loops

Arrowslits or Loops were an inevitable part of medieval castle battlements and thus its defence. A medieval castle arrow-loop was a narrow opening in the medieval castle walls and towers and was used to launch arrows at the invading enemy.

Medieval Castle Parts *Machicolations

Another important feature of a medieval castle parts list is called a machicolation. Medieval castle machicolations were projecting platforms at the top of castle walls and usually protruded from the walls.

Castle Machicolations can be seen at the top of this castle wall, there are machicolations around the tower as well

The openings that jutted out from the castles walls could be used to drop stones, boiling oil or water, excrement, and various other materials on the enemy. The machicolation could either run along the entire length of the wall or could be positioned around a tower or smaller part of the wall in a vulnerable area.
