Longleat Safari Park, in Wiltshire, England was opened in 1966 and was the first drive-through safari park outside of Africa. The park is situated in the grounds of Longleat House, the home of the 7th Marquess of Bath and a tourist attraction in its own right. The safari park was the first of its kind anywhere in the world and was considered to be a massive breakthrough in the way in which captive animals were kept, with the animals roaming freely and the visitors in cages (cars).Today Longleat's collection comprises over 500 animals, and the whole estate is situated on 9,000 acres (36.42 km2) of Wiltshire countryside.
