Visitors are to be given the opportunity to experience Windsor Castle's Round Tower as part of a new guided tour to run in August and September.
Between 1 August and 30 September, the tour will enable the public to access the top of the 840-year-old tower overlooking the castle and surrounding parkland.
The 'Conquer the Tower' tour will also include the external 'gallery' at the base of the building's drum, which is equipped with 16 bronze field guns from the 18th century.
