Portcullis

Portcullises were vital defense mechanisms in medieval castles, originating from Roman times. They trapped enemies, aided in rapid deployment, and featured spiked ends to injure attackers, enhancing castle defense strategies.

Portcullis

The portcullis in a medieval castle was a crucial defense mechanism made of metal and strong wood, designed to quickly slide up or down grooves to secure the entrance during attacks. Originating from Roman times, it became a common feature in European castles from the 12th century onwards. Castles typically had two portcullises strategically placed to trap enemies and allow defenders to attack from above. The winching mechanism enabled rapid deployment, aiding in trapping intruders. Castles with multiple portcullises could strategically stop and deal with enemies by luring them inside and dropping the gates simultaneously. The portcullis played a vital role in castle defense, allowing for organized responses to ambushes and sieges. Its spiked ends could injure attackers when dropped, adding to its effectiveness as a defensive structure.

> For example, soldiers could drop hot oil from holes in the ceiling, while archers and crossbowmen could shoot missiles from arrowslits on the sides.

The Santa Barbara County Courthouse, despite having been constructed in 1926, incorporates such holes and slits. I don't think opposing counsel has ever had boiling oil dumped upon them, but at least the architects (and tradies?) had a bit of fun putting these in.

The only reason why I already knew the name of this type of gate was because Fezzik was ordered to prevent it from closing in 'The Princess Bride'. Porte cochere are very common in my neighborhood as there's a zoning requirement for all garages to be behind the primary residence, but so far, I've yet to see anyone equip one with a portcullis.

> They were an essential defence mechanism, as they allowed the castle to be organized when facing an ambush.

How do you "ambush" a castle? Perhaps TFA meant "siege"?

They lost me at dropping hot oil. There is no evidence of anyone dropping oil, it would have been expensive and hardly better than boiling water.

For anyone interested in this sort of thing this 5 part blog series from ACOUP on fortifications is really interesting.

The 3rd part specifically goes into castles.

"Portcullis" seems somehow much more deadly than "sliding door"
