The Wallenstein Gardens may have a lot of rules, but the lack of human and canine detritus adds to their beauty. Famous for the peacocks, the cavern-like folly (look for phallic and serpentine motifs) and the biggest fish we’ve seen in a while – ducklings often have to make a sharp exit to avoid being nibbled. An owlery, beautiful frescoes and benches galore for whiling away sunny afternoons. Look for the secret entrance next to the metro exit.
