The camp ground even has a mini 'Big Ben' tower
Harewood House is home to an international camp for Guides from many countries.
The week-long camp will be host to over 5000 UK Guides and another 2000 overseas visitors.
The Girlguiding UK Centenary Camp will be held between Saturday 31 July and Saturday 7 August 2010.
Even a snow slope and a sandy beach have been specially constructed in the grounds of the stately home for the organisation's biggest ever Guide camp.
Harewood House is the former home of HRH Princess Mary, The Princess Royal, who became President of The Girl Guide Association in 1920.
Princess Mary died at Harewood in 1965 and the former Housekeeper's Room in Harewood House now has a permanent display of her life and work including her involvement in Girl Guiding.
Around the world
Organisation of the event took years, Sue Taylor is lead volunteer (right)
Centenary Camp Director Hilary Cooper has been planning the event for four years and those attending the camp have travelled to north Leeds from around the world.
The Bangladeshi group spent two days travelling from Dhaka, via Delhi and London. And the Australian group have covered around 13,000 miles to reach Harewood.
Over 40 countries are represented including Mexico, Nigeria, Portugal and Thailand.
Some of the campers have come from much nearer home, Alwoodley to be precise, just a few miles from the camping ground. Roisin Brophy from 1st Alwoodley is quoted in The Daily Gem, the camp's own newspaper, as really looking forward to more snowboarding lessons.

It was in 1909, that Robert Baden-Powell agreed to let girls have their equivalent of the Boy Scouts. It was a time when women couldn't vote, couldn't work once married and couldn't borrow money.
During the First World War, Guides worked in munitions factories and in the Second World War, young women in the Guides International Service worked alongside British soldiers to help Jewish inmates liberated from Bergen-Belsen concentration camp.
At the heart of the Girl Guides' ethos is the commitment to helping others and being a good citizen.
