A neolithic monument which - legend has it - contains the remains of King Arthur's magical mentor Merlin is to be restored.
Exclusive boarding school Marlborough College, in whose grounds The Mound is located, applied last year for planning permission to demolish 20th century buildings that cut into the side of the nationally important monument.
Now, Wiltshire Council has given the go-ahead for the offending carpentry workshop, toilets, plant room and water meter and pump to be demolished.
A 2024 archaeological assessment said that while it is unlikely anything archaeologically significant would be found under the buildings, removing them would enable archaeologists to investigate a cross-section of the mound.
According to the plans, there is "good potential to encounter traces of the medieval and post-medieval waterways" during the proposed works, which are set to leave a more "visually pleasing" setting for the monument.
The Mound was built 4,000 years ago and, at 60ft tall, it is second only to nearby Silbury Hill in terms of height for such a monument.
According to local legend, the wizard Merlin is buried in the mound, giving the town its motto - "'ubi nunc sapientis ossa Merlini," or "where now are the bones of the wise Merlin".
Following the Norman conquest, William the Conqueror ordered a castle be built on The Mound.
In the 1980s a teacher at the College supervised the renovation of an 18th century shell grotto, which had been dug into the side of the hill.
And in 2016, trees that had seeded on the hilltop were removed.
In 2000 the Marlborough Mound Trust was formed to conserve and restore the monument.
The Mound is not open to the public, although an annual Open Day is held each summer, for which tickets are issued.
Former pupils of the £62,000 per year school include the poet John Betjeman, author Dick King-Smith, war poet Siegfried Sassoon, singer-songwriters Chris de Burgh and Nick Drake, comedian Jack Whitehall, the politician Rab Butler, and royals Princess Eugenie of York, and Catherine, Princess of Wales.
