Fodor's Expert Review Nikolaj Kunsthal

Though the green spire of the imposing Nicholas Church—named for the patron saint of seafarers—appears as old as the surrounding medieval streets, it's actually relatively young. The current building was finished in 1914; the previous structure, which dated from the 13th century, was destroyed in the 1795 fire. Today the church is a contemporary art gallery that often has good exhibitions.
