The Schmetterlinghaus, also known as the Imperial Butterfly House, is a hidden gem in the heart of Vienna, just a stone's throw away from the opera house. Inside this stunning Art Nouveau palm house, visitors are transported to a tropical oasis filled with around 400 free-flying butterflies. It's like stepping into a magical world where these colourful creatures flutter gracefully amidst waterfalls and exotic plants.
