A gate on the northern side of Prague Castle leads to the Powder Bridge (Prašný most; 1540), which spans the Stag Moat and leads to the Royal Garden, which started life as a Renaissance garden built by Ferdinand I in 1534. It is graced by several gorgeous Renaissance structures.
The most beautiful of the garden’s buildings is the 1569 Ball-Game House, a masterpiece of Renaissance sgraffito where the Habsburgs once played a primitive version of badminton. To the east is the Summer Palace, or Belvedere (1538–60), the most authentic Italian Renaissance building outside Italy; to the west is the former Riding School (1695). All three are used as occasional venues for temporary exhibitions on various subjects.
