The Ark of Bukhara is a spectacular-looking fortress located in Uzbekistan, built 1,500 years ago

Damn, those layer lines are clean. Link to STL?

The layer shifting is pretty severe in this print!

In case you were curious, like is was, the walls are 16 to 20 m (52 to 66 ft) tall.

I wonder, the walls may be even thinker than they are tall at the bottom

Hard to understand the scale.

According to the Wikipedia article on the history of Bukhara:

After the fall of the Kushan Empire, Bukhara passed into the hands of Hua tribes from the Mongolian steppe and entered a steep decline. However, the 5th century saw an unprecedented growth in urban and rural settlements throughout the entire oasis. Around this time the whole oasis territory was surrounded by a more than 400 km long wall.

I assume this structure dates to that period of construction?

I wonder whether this Kushan empire is the inspiration for the name of the protagonist’s tribe in the Homeworld videogame series.

Was there any advantage to having it lean like that?

In defensive terms, no, not really. They had to build it like this because these aren’t really walls per se, it’s just brick lining on the outside of an earthen mound, and mounds are, well, mound-shaped. https://gomadnomad.com/wp-content/uploads/2013/02/Bukharas-Ark-Palace.jpg

It would’ve made siege ladders harder to set up.

Who needs siege ladders when you can just climb up the damn wall?

You’d think there’d be a reason beyond construction requirements, though—otherwise someone in the past 1,500 years would have replaced it with a more conventional wall.

They did. This is only the oldest, innermost fortification in the city. AFAIK additional layers of walls were build around it later.

Is it a lean, or is it wider at the bottom?

This question confuses me geometrically

is it \ or △ shaped ?

Not this one, but newer forts were built with angled walls to help protect against canon balls and the like.

But there the walls were still vertical to the ground yeah?

Harder to knock down or undermine?

You’d think it would lean the other way to make bit harder to climb.

Edit: or this could be a view from the inside. Or maybe the goal is to keep people in rather than out.

Edit again: none of these things seem true according to Wikipedia. It’s curved inwards and it houses the rich, so it seems to just be aesthetics.

Are we sure they built it like that 1500 years ago? Churches can suck down in the span of only a few hundred years.

Wikipedia says it was built around the 5th century

The whole thing is basically a wall-clad hill. heaping one stone onto another is something they managed even thousands of years ago. And the climate (it is an oasis in the desert) is dry enought to keep it from eroding.

Well clearly it’s because the castle defenders of that era were quite sophisticated, but simply don’t dance they just pull up their pants and do the rockaway.

Harder to get on the wall would be my guess

Seems to me it’d be a lot easier to scale this incline than a vertical wall

What does it take to get you very interested? This is pretty amazing to me.

This is for strictly mildly interesting material. If it’s too interesting, it doesn’t belong. If it’s not interesting, it doesn’t belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh… what do we know?

Just post some stuff and don’t spam.
