A spate of vandal attacks at a Victorian gothic mansion in Cardiff has led to calls for CCTV to be installed.
But because Insole Court in Llandaff is a Grade II listed mansion house it needs special permission for cameras to be set up.
Windows have been smashed during the latest of several attacks.
Building owner Cardiff council said it was "dismayed" at the latest damage and would be looking at further action to protect it.
The mansion and estate, off Fairwater Road, was built in the 1850s by the coal and shipping owning Insole family and has been under local authority ownership for more than 70 years.
It is used as a community centre and many adult education classes are held there.
Sue Caldwell, who is on the committee of the Friends of Insole Court was upset to discover the latest act of vandalism.
"I went up there to take the dogs for a walk and I could see the council vans were there and they were boarding up the windows," she said.
"It is so frustrating and everyone is concerned about it.
"There is a general feeling that the council should be doing something more to try and stop this – like putting CCTV up.
"It is heartbreaking to see the building being destroyed like this because there aren't many beautiful old buildings left in Cardiff anymore".
Police in Cardiff confirmed that they had had two reports of misbehaviour involving a gangs of youths in the area in the early hours of Saturday morning but had not had any reports of vandalism at the site.
A spokesman for heritage body Cadw said that in order for CCTV to be installed, the council needed to apply for building consent before going ahead.
A Cardiff Council spokesman, said: "Over the years we have sought to protect and look after this valuable Cardiff asset and are dismayed at the recent bout of vandalism.
"We deplore the mindless minority who are responsible for this and remind them that it is community asset for everyone to use.
"Their actions damage the community as much as they damage the building.
"We are constantly reviewing how the building is looked after and will again consider further actions in the light of this most recent incident".
