Medieval Facts: Why Were Castles Built on Hills?

why were castles built on hills

So, you’re on a fabulous vacation, taking a trip to see a castle. But it’s just going on for too long. You spot the fortress at the top of the hill, but it seems like you are not getting any closer. At a certain point, a question pops into your head — why were castles built on hills?

Building a fortress on top of the hill offered many advantages. Making the castle highly inaccessible and displaying the king’s power were only some of the reasons for having a stronghold on high ground. Keep reading to discover why many castles were constructed on a hill.

7 Advantages of a Castle on a Hill

Advantages

Imagine yourself as a king or a queen, and your next order of business is to build a castle. What would be your top priority? If you gave it enough thought, the answer would undoubtedly be security.

Being able to fend off enemy attacks was crucial to every Lord and Lady. And the hills provided this security more than any other place.

1. It’s Hard to Reach a Castle High Up the Hill

If you had trouble reaching the castle on your tour, imagine how a soldier in full body armor felt.

Attacking a castle also meant carrying a whole lot of equipment — including weapons, a battering ram to break the main gate, etc. Transporting all of that would be difficult even on a flat surface, let alone a hill. That’s why the higher ground was a perfect place for a castle.

Another advantage of a castle on a hill is that it was extremely hard for enemies to approach it. They had to go a long way up the hillside, which made them slower in their advance. Because of that, they were more vulnerable to attacks from the castle.

2. Great Vantage Point

Because the castle on a hill was the highest point in the surrounding area, guards in the watchtowers could see miles in the distance. That was useful for spotting the enemy as early as possible.

The lookouts could then warn the army, and the soldiers would have enough time to prepare their defense. This early warning system could not be possible if the fortress weren’t on a hilltop.

3. Underground Security

Another answer to the question “Why were castles built on hills?” is that hills offered you protection from an underground attack. After all, a hill is one huge rock that no one could penetrate. If you built your castle on a hill, the enemy could not count on digging beneath your castle and attacking you from below.

4. A Rocky Hill Is Dangerous to Climb

Not only were castles built on a hill, but they were also usually built on a rocky cliff. And entering the castle via a cliff wasn’t the best idea. Firstly, it was easy to fall off the cliff. A rockface, you will agree, is very hard to climb on its own. Now add the battle equipment that weighs you down, and falling to your death is all but inevitable.

Secondly, even if the soldiers could manage not to fall off the cliff, they would still be easy targets. They had to watch their every step when climbing, which made it easy for the archers to rain a storm of arrows on them. The invaders could not defend themselves or counter-attack, so any charge on the castle in this way was destined to fail.

It comes as no surprise, then, that building a strong main gate was a priority because that was the only way for enemies to attack. They could not invade from underground, the sides, nor the air. So they had to worry only about constructing a secure front door — all because the castle stood on a hill.

5. No Spies

Enemy spies couldn’t get higher than the castle to gather information. The only way for them to see what people in the fortress were doing was to climb the walls, which was an almost impossible task.

6. The Castle Would Stay Stable

Castles deteriorate when they aren’t built on solid ground. We have seen this throughout history. You won’t have this problem if you construct it on top of a rock, as it will remain stable and strong for centuries to come.

7. Power and Prestige

Monarchs didn’t think only of military advantages when building castles. Kings and queens were always hungry for power and prestige. They went to war for them, conquered countries, built empires.

But most of all, they took pride in their strongholds. When they constructed their castles, monarchs wanted them to represent the royal family that constructed them.

Building a castle on a hill added to this feeling of power that monarchs desired so much. The fortress was the highest object in the whole area, making it a symbol of great power, as nothing could challenge it.

Additionally, the castle appears more beautiful when it stands on top of a hill. Its peaks touch the sky, unmatched in its beauty by anything surrounding it. Much like we admire them today, the folk of the time did so too, maybe even more.
