oops, I allready played around with a copy I made from the screenshots. :D

This is indeed a quite interesting building - I mean the ancient asturian church of
San Miguel de Lillo that inspired Peak.
Sadly I havn't been able to visit it yet but it has been on my list of places I want to visit for quite a while now.
Especially since some newer studies about it make some quite exciting claims and have added some interesting theories about the early design grids and measuring units used for such important buildings.
For those that might not have noticed, the building we see today is but only a fragment of the original church that was probably three times the size of the current building. What is left is the narthex (the old entry loby) with a raised platform and the first bay of the main hall, originally consisting of three aisles. Although there have been excavations that offered clues on the general size of the church there has been some despute on the exact design with
several different reconstructions offered in the last century of research.
As such I tried a reconstruction in Minetest, using Peaks design. I did add a block to the narthex, so that I could place the buttresses of the transept-like parts in line with the upper walls. I did use Peak's vertical layout though, rather than the real hights - just because I was lazy.

The wall plan to the right is based on a church of the same time frame excavated somewhere to the north of Frankfurt am Main iirc.
The inside is not worth showing yet and will be far from the postulated original splendor
shown in this animation
Knowing what the original design was about I found the variations on the building relict quite fascinating. Especially the way Peak turned the main facade to a side and opened up the rather dark original design with windows and porches, turning the preromanic religious building into a neogothic house or a lofty elvish abode.
Just a mere 100m away lies
the old palace hall of Naranco. Maybe another interesting building to play with in Minetest? (hint-hint)
