Marton Oak

The Marton Oak is a large, ancient pedunculate oak (Quercus robur) in the village of Marton, Cheshire.

The tree's girth (as far as it can be called a girth, the tree being quite fragmented) was measured by Pollard (in August 2025) as being 14.6 metres (48 ft) at 1.5 metres (4 ft 11 in) off the ground, making it the UK's largest and widest tree since the collapse of the Newland Oak in Gloucestershire, surpassing trees such as the Bowthorpe Oak in Lincolnshire and the three large sweet chestnut trees at Canford School, Dorset. The tree is believed to be 1,200 years old, and is thought to be in the latter stages of its lifespan, as most of the heartwood has rotted away. The tree split into sections centuries ago, but they have one and the same root system. It is not known what the tree looked like before it split.
