This has come up in relation to our day out at Clonmacnoise but does anyone know the legalities of photographing historic sites in Ireland?

The Clonmacnoise visitor centre said permission is required from the Office of Public Works to sell any images of the site.

Does this apply to all historic sites?

Are all historic sites under the control of the OPW?

Are there any sites that you would be forbidden to photograph in the first place?

I need to check this out and plan to ring the OPW but I thought I would start here to see if any members have experience of this sort of thing. Maybe Sile has come across this issue during her tours?
