[@VeritasOmniaVincit176]

Hohenzollern Castle in Germany has a very interesting defense feature in its entrance: multiple “snail” shaped ramps that lead to the next redundant gate. I counted at least three instance where attackers would have to breach one gate, only to climb a 360° ramp for the next level (while being fully exposed to enemy fire) only to find yet another closed gate. The fact that there are no straight paths to the gates makes battering rams impossible to be implemented against them.

Excellent work. One point about moats being 'open cesspools' though. They weren't. They were fish ponds. Human and food waste was put into the ponds, which was broken down by algae which fed the fish. It is still common in rural Vietnam for example. Cities in Europe used such ponds to deal with waste as late as the 19th Century, until the population became too dense.

[@flashgordon6670]

They would’ve become cesspools in times of siege. When everyone crammed into the castle and the attackers would deliberately pollute the water with dead rotting animals and faeces.

[@flashgordon6670]

Bribery and spies were a common way to get through drawbridges and or gatehouses. Attackers can also fire huge rocks from Trebuchets and catapults at them, build ramps and use battering rams, or a multitude of other ploys. That’s the sheer beauty of castle sieges, the imagination is the limit for both attackers and defenders. The most imaginative and inventive side and the one that prepared and had the most supplies, usually won the battle. Most siege outcomes were determined by illness and starvation. Whoever lost the least soldiers and had the best hygiene and food quality, would inevitably come out on top over a longer siege. And also which side could get reinforcements and relief from allies and supply chains. One of the most epic sieges of all, was the siege of Jerusalem in 70 AD by the Romans. There’s many fantastic videos about it on YT. There’s a 3D virtual reality modelling video of it that I saw some years ago. Also the last hold out of the Jews by the Dead Sea, was another all time epic siege. I won’t say what happened at these two sieges, bc I don’t want to spoil them for you, but you will be awestruck trust me.

This is the most comprehensive video I've seen on castles! It was a pleasure to watch :) I was wondering, does anyone know how the people assaulting a castle lowered the drawbridge? Aside from climbing the walls, have any attackers ever lowered a drawbridge from outside a castle? Or possibly bridged to a raised drawbridge and broken through it?

[@KobeanHistory]

I haven’t looked into it in depth yet but I heard that with smaller drawbridges using exposed rope to lift them, it was possible to shoot the rope with arrows and open the drawbridge that way. Ive also heard of attackers filling the moat in a certain place to get to the castle wall so I imagine they could have done this at the gatehouse as well and break through the drawbridge that way. It is something i will look into further for a video in the future

Hunterston Castle in Ayrshire Castle is from 1263 AD. Made to prepare for the Battle of Largs. It is the best preserved Pele Tower in Scotland and still owned by the original Clan Hunter family. I made the longbows and warbow forvthe Castle in 2014 and shot them on the estate 180 yards in a Clout meet with the Ancient Society of Kilwinning Archers, which I was a member of at the time.

[@1joshjosh1]

Your videos rule and the historical content is amazing but just 1 little suggestion. Other than the castle in Syria( I got to go to the krak pre-war) and when you specifically name the place you show all these beautiful pictures but I don't know where they are. Maybe just a small label corner of screen.

[@greggweber9967]

Attacking the castle in Perpignan France, after entering the gate and passing under the murder holes, you turn left and go up irregular steps. Archers are shooting arrows from i think all sides. At the end, you turn 180 degrees to the right and continue going up. Eventually, you are at the top, which is the ground level outside the smaller residence castle for the king of Majorca.

[@laurean5998]

44:45 I assume the portcullis would be either wedged or simply blocked by a beam to prevent it getting lifted up. Saying it would be easy to lift it is only true if you have the element of surprise and it is not locked. I also assume the chapel in the gatehouse was meant to prevent any devil or whatever from entering the castle as they couldn't enter the house of god

I didn’t say there weren’t castles before the Normans, I said Normans introduced stone castles.

[@edi9892]

What's the point of having a round or semicircular barbican? Unlike circular towers, I see the shape here more as a disadvantage in terms of distributing fire. I'd rather have it a small castle with round towers, or make it triangular to concentrate the fire while keeping the dead angles at a minimum. BTW: I missed a concept, we call Zwinger. It's a narrow section with two separate gatehouses. It can be a small yard, a barbican, or a part in between the inner and outer wall. The key factor is that you need to cross it and break through the second gate and while doing so, you'll be attacked by archers from three if not all sides! The craziest iteration of it is the double spiral of death in Hohenzollern castle (two yards with a ramp spiraling up to the level of the main castle)

[@larrywave]

Great 😇

[@MeEncantaKiley]

I think most castles had a main gate, but for smaller items, or maybe even people they can hoist them above the wall, to avoid risk of leaving the gate open.

[@markfillery1002]

the round arrow slits were gun ports or cannons so later in design.the draw bridge at dover is an internal gate so not very defended not a main defence i think the main gate house is the 2nd and behind that wall so it leads to a court yard dover has 2 or 3 walls and was breached but the english held off the french and filled in the breach in the wall.the solid portcalis may be later and to defend from musket fire as an open lattich design you could fire though

[@edi9892]

I think that I've seen examples of gateless castles. However, if you'd call them a castle is a different story... The ones I'm thinking of were not much more than a single tower, or house on top of a rock. I have no idea how they were constructed in the first place, but it probably included a 30m climb... Anyway, they were somewhat common in the German-speaking areas. However, a far more common castle form that shares two similarities were church-like castles. In the same region, we had a lot of castles that often didn't even have a walled-in section, but were merely a house (timber frame, or stone) with an accompanying keep. This keep usually had no entrance in the ground floor, but a hand-cranked elevator to the ground floor. This windowless room on the ground floor could be used as a prison cell, but more likely as a vault for things that you would want to keep safe. Quite commonly, this castle had not much more than a great hall above some stables and above the vault, there were a few more floors with the private chambers of the lord, possibly a room for the scribe, and a weaponry and a lookout.

[@mohamed-fb9vt]

Hello sir Do you have any pictures or old depiction of those keep with hand cranked elevator ?

@@mohamed-fb9vt I can't remember where I've seen a reconstruction. Maybe it was good old Violet LeDuc. Anyway, I've seen castle ruins where there were the tower had a room that could only be accessed from above, be it via a ladder or an absurdly steep stairway, this I cannot tell. In any case, you can still find many timber frame houses even in cities that had a hand cranked cargo lift. It's always the top window and below the remains of a pulley. I bet that these towers had something similar and probably a ladder.

A bartizan can be classed as a turret but not all turrets are bartizans. A turret can be generally defined as a tower or part of the defense that is elevated from the rest, while the bartizans most defining feature is that it overhangs from the wall.

@14:06 I have to question the validity of what you're saying. The muzzle shouldn't come out past the wall, you say, to avoid detection? I find this statement hard to believe. In modern combat, this is true, for several reasons: in modern combat, when people shoot from buildings, these buildings don't have arrow slits; they have massive windows and the walls around them aren't bullet proof either, so it's important in modern combat for a shooter not to expose himself with the barrel of his gun. Much less true for people in stone castles firing through arrow slits. The 2nd objection I have is the old-fashioned gun powder they would be using in the case of firearms and canons (which were the weapons being spoken of at 14:06). This propellant gave off massive plumes of thick smoke in every shot. I find it very hard to believe that they'd prefer to keep this inside of their fortification.

[@ViolletLeDonPin]

I believe they actually fired from inside the building, over the smoke, most castles, to my knowledge, had some air outlet for smoke from guns, like windows, ducts or chimneys

Some of them started as Roman earthen forts that could place the beginning close to the birth of Christ. What makes the European structures castles that the Turkish structures do not fit in that category?

[@KobeanHistory]

If I remember correctly (correct me if I’m wrong), those were built as more of a communal defence. One of the defining features of a castle is that it was the residence of a lord or noble. Which sets it apart from a fortress or citadel.

[@2adamast]

Even in early europe, the romans mention gallic defenses made of stone backed by wood. Back then the romans see castellum as smaller than castrum and not by the presence of a small unelected war chief, still holds in early medieval period. Or later as for example Richard last castle siege (Châlus) isn't about the residence of a noble.

I still struggle to understand machicolations. I've never seen any examples that were in their original form. I could imagine two different versions: 1) Putting trapdoors or wooden planks on top of the holes so that you cannot fall through (especially, when you're in low-light situations, or high-stress situations). It would offer more space and allows you to get directly to the wall, which gives you a wider field of view. The disadvantage being that you would need to manually remove the cover if you wanted to attack below, which would take time and potentially alert the opponent. 2) Putting a railing behind the holes. In that case, you can rest your crossbow or musket on the railing and you can quickly switch between firing far or down. The disadvantage being that you're further away from the loophole, which makes your job harder and the battlement would be more cramped...
