Dyrham Park aerial walkway to view roof replacement work
An aerial walkway has been built at Dyrham Park near Bath to allow visitors to see the work being carried out to replace the mansion's roof.
The walkway, with two viewing platforms, has been built inside the covered scaffolding and circles the whole building.
Some 46 tons of lead and 8,000 slates on the 150-year-old roof are being replaced under the £3.8m scheme.
The Grade I listed house attracts more than 160,000 visitors each year.
Up to 90% of the joints at the National Trust-run property are leaking and plastic buckets have been used to catch the falling water.
Dyrham Park was built between 1692 and 1704 by William Blathwayt who was a principal colonial administrator and the Secretary at War for William III.
The mansion houses a collection of 17th Century Dutch furniture, art and ceramics.
