Works on the historic Conwy Castle have been extended until November.

Work including removing vegetation from the castle walls and ensuring no stones are loose has been ongoing for the past few months and was expected to be completed at the end of the summer.

These works have seen scaffolding covering various sections of the castle for months.

As the project progressed workers found additional work would be required in the North-West and kitchen towers pushing all scheduled plans back.

A CADW spokesperson said: "Whilst carrying out the conservation works to North-west and Kitchen Towers, additional high-level works were identified and carried out which had a knock-on effect on our programme.

"The works carried out are to a very high standard and Cadw are keen to see this exemplar continue.

"Conservation works to the East Barbican – carried out by rope-access personnel - are on-going and are programmed for completion by the middle of November; the scaffold continues to be removed as soon as possible, exposing conserved fabric to visitors and locals alike."

The structure was built for Edward I, by Master James of St George, and is said to be amongst the finest surviving medieval fortifications in Britain.

An estimated £15,000 was spent building the castle, the largest sum Edward spent on any of his Welsh castles between 1277 and 1307.

The castle includes two fortified gateways, eight massive towers and a great bow-shaped hall all set within its distinctive elongated shape.

On the inside there is an outer ward containing a great hall, chambers and kitchen, and a more secluded inner ward with private chambers and a royal chapel.
