Throughout Human Civilization wherever people have existed in treed environments, Trees have always featured prominently within the societal structure. They serve as meeting places, centres for village markets, & even secret & romantic rendevous.
Many Cultures such as the ancient Celts, honour trees such as the Oak, Yew, Rowan & Ash as Sacred. They represent the divine Mother Earth.
