These are from the Imperial Cathedral Speyer, a church of much grander scale than Heiligenstadt, and built in pure Romanesque style.
(It reminds a bit of the Aula Palatina in Trier,
esp. considering the fact the latter had murals in Roman times.)
I mentioned in the first post
that St.Martin's main nave looks higher because of the unadorned walls. Speyer is so large that they masons didn't need such tricks, thus the walls are structured by double arched windows and frescoes. The murals are not original, but there have been paintings in the Middle Ages. Crossing dome
I took the photo for the effect; I'm experimenting more these days. The angle doesn't show how high the crossing dome is - one of these days I'll look up the measurements for Constance. *grin* Crypt, detail of the ceiling
A fine example of Romanesque gross grain vaults with perfectly semi-circle arcs. A bit dark, unfortunately; the light in the crypt was very Mediaeval.
