Sewage threatens ancient cave carvings
Published on May 21st, 2009 | by Admin0
The cave, which is situated below Melbourn Street, will be closed for three weeks next month while experts from English Heritage investigate the state of preservation of the cave and to determine how much damage has been done to the carvings over recent years.
“The cave is hewn out of the soft chalk, and the carvings can be affected if the atmosphere inside becomes too humid or conversely too dry. Vibrations from the road can also affect them. Drainage is also a big factor so this will be an important part of the survey.
