St Nikolaj is a Roman Catholic church, built in 1969. Unusual for a church, it is built of aerated concrete. Its innovative square-shaped design by Johan Otto von Spreckelsen served as a basis for his Grande Arche in Paris. The dimensions of the inner cube of St Nikolaj Church are very close to those of the "holy of holies" in Solomon's Temple as described in Ezekiel 40:5.
