Orissaare Oak Western Estonia & The Islands

Even in a nation where people still leave offerings in sacred groves, Orissaare's most famous landmark is, well, a little weird. Winner of the 2015 European Tree of the Year award, this 150-year-old oak stands right in the middle of a football field. The field was laid out around the oak in 1951 and when tractors came to remove the tree, the tree won the battle (although it still bears the scars). Players simply kick around it.
