Westonbirt Arboretum is in Gloucestershire on the A433 approximately southwest of Tetbury, at Ordnance Survey . Music and Festivals From 2003 to 2005 the arboretum hosted Britain's first designer-led garden festival: Westonbirt Festival of the Garden. On 16 July 2011, Irish vocal pop band Westlife held a concert for Gravity Tour supporting their album Gravity. Also in 2011, Treefest was launched. Following several successful years of the Festival of the Tree event, Westonbirt Arboretum refreshed the popular August bank holiday event with camping, music and more activities celebrating trees and nature. Christmas and the spectacle of bare, sculpted trees in winter is celebrated at the Enchanted Christmas event. From the end of November and throughout December, an evening illuminated trail runs throughout the Old Arboretum, highlighting the beauty of Westonbirt's trees in winter.
