King Alfreds Tower, Stourton, Wiltshire, UK.

King Alfred's tower is a 160 ft high triangular brick folly designed in 1765 by Henry Flitcroft and completed in 1772 by Henry Hoare II. It stands on Kingsettle Hill, in the parish of Brewham, on the Somerset / Wiltshire border, as part of the Stourhead estate.
