Buçaco Forest

Buçaco Forest is an ancient, walled arboretum in the Centro region of Portugal and home to one of the finest dendrological collections in Europe. The forest measures 1450 meters by 950 meters and covers an area of 105 hectares; the perimeter wall is approximately 5 kilometres in circumference and punctuated by a series of gates, one of which bears the text of 17th-century papal bulls forbidding women to enter and threatening to excommunicate anyone harming the trees, though neither stipulation is currently legally binding under Portuguese law. More than 250 tree and shrub species grow in the forest, including huge centenarians and exotics introduced by Portuguese mariners during the Age of Discovery. In 2004 Portugal submitted Buçaco Forest to UNESCO's tentative list of World Heritage Sites. ()
