In the village of Tolpuddle in Dorset, England grows a sycamore tree, under which six English farmers, known as the Tolpuddle Martyrs, formed a trade union in 1834.

They were accused of violating the Unlawful Oaths Act of 1797 and transported to Australia. However, a public outcry led to their release and return to the country. The tree's age is dated 1680, and its trunk circumference is 5.9 m (19,35 ft).
