On 9th June 1977, the Queen officially opened the Silver Jubilee Walkway, a 21 km walking trail around central London to mark her Silver Jubilee, or 25 years on the throne. Thirty-three years later, work is under way to celebrate the Queen’s Diamond Jubilee with a new 60 km walking trail, the Jubilee Greenway, providing walkers with a kilometre to walk for every year of the Queen’s reign.
