The BTO has created a quiet and accessible retreat in the grounds of their Thetford headquarters - a 12th century nunnery - with a series of beautiful, wildlife-friendly gardens. Each garden features a range of plants and habitats to attract a variety of wildlife, including birds, butterflies, dragonflies and bees and includes areas to rest and enjoy the surroundings.
