Restoration work at a 13th century former stately home has reached a significant milestone with work ongoing to secure the building.
Huge lintels have been lowered into the ruins of Astley Castle in Warwickshire to save the building from collapse.
The building is undergoing a £2.5m restoration and the lintels mark the halfway stage. Work is due to finished in autumn next year.
The castle has been home to three Queens, including Lady Jane Grey.
Elizabeth Woodville, Queen consort of Edward IV, and Elizabeth of York, Queen consort of Henry VII, have all lived there.
Project manager Dave Marsh said the castle's restoration had to be one of the most complex and fascinating projects in the UK.
"The 4 tonne, 7 metre long concrete girders, manufactured in Bury St Edmunds, will be lifted up to a height of 20 metres over the surrounding landscape and then transported over 50 metres and placed inside the existing castle walls using a giant crane," he said.
The castle was being used as a hotel when it was devastated by a fire in 1978.
Funding for the restoration has come from the Heritage Lottery Fund, English Heritage and private individuals.
