Same reason why their facades are usually so intricate. Because they thought it looks good, makes them look grand, makes those underneath them feel small etc., and had the funds to make it so.

To impress the poors.

But, in spite of the big buildings, the filthy rich are the same size as us, and we outnumber them by billions. They have billions in dollars, we have billions in people. They'll lose hard and they know it if we ever get over our petty differences and focus on the true enemy in our midst. Hence the reason they do everything in their power to keep us divided over everything they possibly can.

Well, because they built them that way.

I don't know how much this generalizes but I know that at the Hagia Sophia in Istanbul, the doors were made large enough for Emperors and then Sultans to be able to enter the building with their horses and carriage.

In addition to the psychological impact, somewhere hot like Italy, very high ceilings will keep the room cooler, and bigger doors and windows will aid in ventilation.

I'm noticing that whole Reddit watermark more frequently.

On one hand, it's disgusting as heck to put in a watermark.

On the other hand, it's pretty effective. People see it, and join that subreddit.

I wouldn't mind Lemmy watermarks if it helps grow the community.

How else were you supposed to bring trojan horses inside? If you’re cold, they’re cold!

When giants used to roam the earth, these buildings were created by people that wanted to treat them fairly

It's probably ties back to Romans and Greeks building temples. Doors were made big so the gods could get through them comfortably and visit.

Wouldn't be too crazy to see the trend continuing because it looks good.

People were much taller back then.

To better fit the royal egos through.

Ha! I kid, I kid.

Most likely, it was mess with people psychologically, adds to a better defense and simply, it looks more impressive than if you were to have a ordinary sized double doorway.

Psychologically because, are you more likely to want to go through a massive double door entryway or a normal sized single doorway? There's wonderment and/or worriment as to what lies on the other side of these doors than others.

I like how out of all of the answers in this thread, no one said high volume traffic.

Almost like a gated city has a ton of people going in and out all the time hauling trade, materials, technology, etc.

If only there was some way to prevent making a bottle neck of traffic and ensuring that large structures can also pass through the wall when needed.

If fantasy/scifi has taught me anything, it's because the ancients were larger than us. You'll also find their technology to be significantly more advanced and mysterious, possibly a cure or explanation to the terrible blight that has fallen over the land.

In addition to the other reasons listed here, it was not uncommon to lead large processions through these doors which often carried large, tall weapons, people mounted on horseback, and other large, tall, banners, regalia, etc. that required high clearances.

This article suggests it's as a display of wealth and power, but also for practical reasons like letting in crowds of people.

It also says:

Earlier architecture relied on heavy pivots and iron strap hinges, requiring oversized doors for structural support. But the development of newer materials and designs allowed for more practical, durable doors without the need for excessive size.

It links to another article about door construction back in the day, if you want to learn even more about them.

The craftsmen of that time probably crafted siege equipment in the city and wanted to get it out on the field.

Because the door dealerships made more money.

Sounds like a yo momma joke.

it's not just about welth it's like having the power to make giant doors from what could be the very best military technology of that time period
