The garden of Spencer House haven't been open to the public since 2011 — but this May and June, there's a rare opportunity to have a snoop.
Built between 1756-1766 for the first Earl Spencer — ancestor of Diana, Princess of Wales — the St James's Place pile is only open to the public on Sundays, and even then, you can't usually stroll around the garden. On 29 May and 5 June, there's an exception to the rule; these two open days celebrate the Year of the English Garden.
Spencer House garden was designed by famous landscaper 'Capability' Brown, and although was much modified since then, has now been reinstated to its 18th century glory.
Tickets for the house and garden (£16 adults, £14 concessions) and garden only (£6) are available from the Spencer House website now.
