The Castle gatehouse was added to medieval castles to make the most vulnerable part of the castle, the castle entrance more secure. By adding a Castle Gatehouse not only was a medieval castles entrance made more secure, it actually made it one of the most secure parts of the castle, if not the most secure part. So the castle Gatehouse was an excellent defensive addition to the medieval castle. The castle Gatehouse created a small building with a passage that had to be entered by the enemy. As the enemy tried to get to the main castle entrance door, they had to get through the gatehouse first which was filled with obstacles and traps and murder holes.

Defending the Castle – Gatehouse
A Castle Gatehouse was strong, usually made of very thick stone blocks, in addition to this it also had some pretty nasty traps for unsuspecting enemies like murder holes built around the top of gatehouse passageway walls, large heavy objects such as rocks could be dropped from the murder holes or hot burning liquids like tar or boiling water. On top of this there were other deterrents built into medieval Gatehouses, the Portcullises for example which was an extremely heavy wooden grille made from strong wood (commonly Oak) sometimes metal plated with iron. The Portcullis could be released at any time and would injure and maim enemy soldiers. Portcullis grilles were also made from solid metal in later medieval times.
The Gatehouse Portcullis was designed to stop surprise attacks from enemy soldiers, it was a heavy metal grilled Gate that was suspended in the air, held by thick rope or chains it could be released in an instant by releasing the holding mechanism of winches and pulleys that suspended it from the ceiling. The portcullises also created a another barrier to slow down or stop battering rams and other siege weapons.

Design of the Castle Gatehouse
Early castle Gatehouses were fairly basic but as the medieval period progressed and knowledge of building techniques improved so did the design of the gatehouse which went from a simple structure to a 2 or 3 storey building. The castle gatehouse needed to be strong but it also needed to look the part to impress other kings, this is why many castle gatehouses are the most impressive parts of a medieval castle and incorporated many features that also helped to protect the castle.
Towards the end of medieval times castle Gatehouses across Europe were transformed into stunning structures that were buildings in their own right. Most castles had one portcullis (heavy grilled gate with metal spiked ends) that was suspended vertically and could be released instantly to stop surprise attacks. The main castle door with was usually made of thick wood would be barred which strengthened it against battering rams and other similar siege weapons. Various other defences were built into the Gatehouse area such as arrow-loops and murder holes.
The Castle Gatehouse could be 3 storeys in height
The Gatehouse top floor was used to store weapons
Murder holes were incorporated into the top floor of the Gatehouse
Guards were stationed on the first floor of the Gatehouse
The portcullis was operated from the First Floor of the Gatehouse
The Castle Gatehouse could include some or all of the the following depending on the date it was built and it’s size.
A Drawbridge that protected the gatehouse from surprise attacks
One or more portcullises, especially on advanced castle designs like concentric castles
Machicolations and murder holes were built around Gatehouses
Arrow Loops and murder holes were built into Gatehouse passageways
A Chapel (usually built in the area at the back of the gatehouse)
History of the Castle Gatehouse
The idea of protecting the most vulnerable part of a defensive building like a fort or castle originated in a period before medieval times (476–1453) in a period referred to as antiquity, this period includes the bronze age and the times of the Roman empire. The entrance to a castle or town were always the weakest link and builders had to come up with ways to make them more secure. As time progressed more advanced gatehouses were designed that became 2 and 3 storey buildings that incorporated advanced defensive features such as murder holes and portcullis which led to the development of the castle gatehouse.

Trapped in the Gatehouse
An attacking army could easily be tricked into entering a gatehouse passages with the entrance being mysteriously open, some castles had portcullis at both ends, the attackers could be lured into the gatehouse, once inside the first portcullis wood or metal plated grille would be released stopping their retreat, the second portcullis at the far end would protect the castle doors. The soldiers who were now trapped inside the gatehouse passage would then be attacked from the murders holes with heavy rocks, hot tar and boiling water amongst other nasty things that were dropped on them without mercy from the murder holes at the top of the walls. Usually crossbowmen lined up along the gatehouse passage walls to fire arrows at the enemy whilst they were trapped.
Did you know this about Castle Gatehouses:
Chapels were built near Gatehouses which attacking armies might accidentally destroy, this would make them an enemy of God.
Concentric castles were a very popular advanced castle design that could incorporate several gatehouses and portcullis as they had several layers of walls and many entrances.
The name portcullis originates from the French word “porte coulissante”
Concentric castles could have several gatehouses and many portcullis built into their complexed design
Some Gatehouses morphed into castles keeps called “gate keeps” the structures built were so advanced they took on a different dimension.
In late medieval times some gatehouse arrow-loops were made into gun ports to keep up with changes to medieval weaponry.
Attacking a gatehouse was made even more difficult because of castle moats and drawbridges
Sometimes gatehouses formed part of medieval town fortifications, perhaps defending the passage of a bridge across a river or a moat
The French term for a small gatehouse is logis-porche (porche) and a large gatehouse was called a châtelet which means small castle.
We hope you enjoyed reading this article on medieval castle gatehouses and would encourage you to look at our other articles on the medieval castle parts page which is linked at the bottom of this page, if you are interested in seeing castle gatehouses in person there are many scattered around Europe, good examples of gatehouses can be seen in France, Germany and York in England which has many gatehouses built into it’s city walls such as the Micklegate Bar.
