Photo's description:

Brunswick Cathedral St. Blasii, painting in the Crossing. The romanesque nave of the Brunswick Cathedral was built between 1173 and 1226. After many additions over the centuries, the original paintings from the middle of the 13th century were rediscovered in 1845. As the conservators in these days felt free to complete missing parts in a historism way, not all the paintings are in their original status. A more detailed description you will find at Braunschweiger Dom Saecco-Malereien (german). The pictured painting in the crossing shows the celestial Jerusalem. Further famous artefacts in this cathedral are a Seven-armed Candelabrum of 4,80m and the Imervard Cross, both from the second half of the 12th century. Nowadays (2017/05) there are intentions to place a second organ in the crossing. If this should happen, the days of seeing the full paintings of crossing and transept will be gone ...
