Hi Elodie, yes - at this link you see the new church to the right, and the ruin of the old one to the left.

https://da.wikipedia.org/wiki/%C3%98stermarie_kirkeruin#/media/Fil:%C3%98stermarie_Kirche,_Bornholm_(2012-07-11),_by_Klugschnacker_in_Wikipedia_(5).JPGAs you can see, there are remnants of two arches in the wall, and this I suppose shows that there have been two vaults, but I can find in detail this in the works of Denmark's Churches*, published by the Danish national museum, but it will take some time. If you or anyone can see other oddities, let us hear ...
If you want to find out more, look for Østermarie Kirke (on the Danish island Bornholm).
*You can read about it here, it is in Danish:
http://danmarkskirker.natmus.dk/uploads/tx_tcchurchsearch/Bornholm_449-487.pdfThey mention a cross-border (korskranke) there has been a door like in ortodoks churches, this can also be seen in another church here.
