Japanese architect Sou Fujimoto developed a very unique building the House of Music in Budapest Park. It was built so it is naturally integrated into the park. The building reminds a canopy of trees, with a lot of big glass windows, there are big holes on the roof. The museum is dedicated to the history of music.
