To celebrate Queen Elizabeth's Jubilee, the .8-hectare (2-acre) Jubilee Gardens were created inside the castle's main entrance. Filled with trees, roses, and flowering shrubs, they were created by Tom Stuart-Smith, a Chelsea Flower Show gold medalist. The gardens are the first established at Windsor Castle since the days of George IV in the 1820s. The gardens extend from the main gates of Windsor to St. George's Gate on Castle Hill. Color is provided by broad swaths of woodland perennials. White rambling roses clothing the old stone walls are particularly romantic.
