The arch was built in 1810 to celebrate the jubilee of George III

Highways chiefs closed a road running under Hafod Arch in Devil's Bridge, near Aberystwyth, last week after a truck was thought to have struck it.

It was built in 1810 by local squire Thomas Johnes to commemorate George III's golden jubilee.

The Forestry Commission, which runs the nearby Hafod Estate, is working with Ceredigion Council to locate the owner.

Last week, the council said it was unsafe for pedestrians or vehicles to walk or travel underneath the stone arch, and put diversions in place on the B4574 road.

A spokesman for the Forestry Commission in Aberystwyth said: "There is confusion over who owns the archway and we don't think it's us.

"We have helped out with repairs in the past, but at the moment we are investigating who owns the monument in conjunction with the highways authority."

After the collision last week, a council spokeswoman said the B4574 road from Devil's Bridge to Cwmystwyth would be closed until repairs had been carried out.
