A 200-year-old tree on a Wiltshire estate has been officially declared the tallest oak in the UK.
The 132.5ft (40.4m) English oak, in the grounds of the National Trust Stourhead estate, was measured by an expert on behalf of The Tree Register charity.
Standing in a clump of tall oaks, the tree's growth has been put down to rich soil and its need to compete for light.
Alan Power, estate manager at Stourhead, said having the tallest oak in the country was "very special".
The champion tree, on the 2,650-acre estate, stands on a sheltered slope surrounded by a clump of six very tall old oak trees.
But unlike other long-lived slow-growing oaks, it is tall and slim, with a trunk circumference of just over three metres.
