This historic viewpoint is much less visited than the popular Observatory Hill, despite only being a short walk away. Named for the solitary tree that stands proud on its highest point, One Tree Hill boasts a magnificent panorama across London and is arguably the better viewpoint for appreciating East London's modern developments.
It has inspired many artists down the years: notably J.M.W. Turner who painted 'London from Greenwich Park', which was exhibited in 1809. It's interesting comparing what Turner depicted back then to the modern skyline of today.
