Westonbirt was originally designed as a private pleasure ground for the Holford family before becoming public property.
Westonbirt, The National Arboretum, is a globally significant tree garden founded by Robert Holford in 1829. It houses over 2,500 different species of trees and shrubs across 600 acres of designed landscape. The collection is organized into the Old Arboretum, featuring historic Victorian-era plantings, and Silk Wood, which offers a more naturalistic, managed woodland experience. The site serves as a vital center for botanical research, conservation, and education. It is managed by Forestry England and is recognized for its extensive collection of maples. The arboretum includes an elevated STIHL Treetop Walkway, which rises to 13 meters above the ground to provide canopy-level views. A central visitor center houses amenities and educational displays regarding the history of the site. The landscape is designed to provide seasonal interest, particularly during autumn for leaf color and spring for flowering blooms.
