Hey, this was part of a game design project I worked on a couple of months ago, inspired by games such as Elden Ring and other Souls-like titles.
The idea for this room was that it would be the location of a boss fight, and halfway through, the bell would fall from the roof, breaking the floor into the catacombs below (hence the bells slightly nonsensical location 
).
The design and composition is heavily based on this amazing piece by do_ra
The ivy was made with the amazing (and free!) Ivy generator by Blenderesse and the rest of the vegetation comes from the Botaniq asset pack.
The knight and hooded figure models came from Sketchfab.

The cathedral is semi procedural, and aspects such as the window placement, column height and width etc. are fully customisable with Geometry nodes. It’s not strictly necessary, but I much prefer the freedom it gives compared to traditional destructive modelling.
In total, it took about 4 days on/off work to get it finished, and I’m pretty happy with the end result!
