The Southern Gardens below the Prague Castle reopened on June 20, 2012 after a 2.5-year reconstruction. The gardens offer one of the most beautiful views of Prague, so they’re definitely worth a visit. They were originally designed by Slovenian architect Josip Plečnik in the 1920s while he was working on numerous projects at the Prague Castle. The recent reconstruction returned the Southern Gardens to their original look. You can access the gardens from the top of the New Castle Stairs off of Hradčanské náměstí, from the top of the Old Castle Stairs near the Opyš viewpoint, or from the third castle courtyard via the so-called Bull Stairs (Býčí schody). The gardens are open daily from 10 a.m. to 8 p.m. and entrance is free.
