Amaliehaven is a relatively new (1983) park near the Amalienborg Palace in Copenhagen:-

From it you could see these onion domes. Onion domes are unusual for Denmark I’d have thought. By searching Google Maps I discovered the building they belong to is on a street called Bredgade. Apparently it is the Alexander Nevsky Church, the only Russian Orthodox Church in the city:-

There are more images of the church here. It would not look out of place in St Petersburg.

This rather grand looking frieze on Toldbodgade seemed to be over an underground car park. The inscription seems to read “Konge May Told Kammer” (King May Customs House?) and below that Anno 1733:-
