Danish architect Arthur Wittmaack was active in København in an architectural firm with Frederik Hvalsøe. Both designed a wide range of typical buildings in and around København that still characterize the city today. Over the years, they changed their style from historicism to neoclassicism and functionalism. In the process, they succeeded in introducing special stylistic features. Wittmaack was the son of a hotelier and studied at the Academy of Fine Arts in Wien (Vienna) after primarily working as a carpenter. On extensive study trips, he visited numerous European countries, the USA, and North Africa. He entered the 1928 Olympics in Amsterdam in the architecture category along with Hvalsøe, submitting plans for the Swimming Pool of Copenhagen. This so-called Østerbro Svømmehal was built in 1926-30 in neoclassical style with gray, polished facades, and narrow windows as part of a sports park to become Denmark’s first public indoor swimming pool. It is still in use.
