Unesco condemns UK for allowing regeneration at six world heritage sites

The United Nations' cultural body voiced alarm about the Tower of London, Westminster Abbey, Stonehenge, the historic centres of Bath and Edinburgh and a Neolithic site at Orkney in a report from its annual meeting.

Only Liverpool's handling of its maritime mercantile city was given approval.

Unesco maintains a register of world heritage sites, and member states can suffer an embarrassing ejection from this list if they fail to maintain them.

Its most scathing criticism was of Edinburgh City Council for allowing the Caltongate development, which Unesco said would mar the Royal Mile.

Views of the Tower of London were at risk of being disrupted by approvals given for tall buildings, as were those of Westminster Abbey.

Unesco said Stonehenge was at risk from the government’s continued failure to divert the nearby main road and improve visitor amenities.

Bath was criticised for the expected effects of the Dyson Academy development on the historic core, and Orkney for allowing wind turbines near to Neolithic monuments.

Bath and Edinburgh have already sought to dismiss fears that Unesco will put a block on major developments.
