The 21st World Scout Jamboree was held in July and August 2007 as part of the centenary celebrations of the World Scout Movement. The event was hosted by the United Kingdom, marking the 100th anniversary of the founding of Scouting on Brownsea Island in 1907.
The Jamboree took place over 12 days, from 27 July to 8 August, at Hylands Park in Chelmsford, Essex. This location was chosen for its convenient access to both air and sea transport, as well as its proximity to Gilwell Park, a site of great significance as a major campsite and training centre for Scout leaders.
More than 38,000 Scouts and leaders from 158 countries with recognised National Scout Organisations, recognition granted through membership in the World Organisation of the Scout Movement, camped at the event. In addition, over 50,000 visitors attended on a day basis, supported by more than 8,600 members of the International Service Team who travelled from across the globe.
