One of the most impressive Art Nouveau structures in the city, it was originally built as the representative pavilion of the Komárov Ironworks for the Prague Jubilee Exhibition in 1891. It was the first cast iron structure in Prague, and today it’s a luxury restaurant with one of the most beautiful panoramic views of the Prague bridges.
