Conwy Castle will open its doors next month, allowing two days of free entry to visitors.

Visitors will be able to enter the castle for free on September 29 and 30, with the doors being open from 10am to 4pm.

Tours will be run on the two days at 11am, 1pm and 3pm.

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.

The castle will also hold Owain Glyndŵr Day celebrations on September 16 between 10am and 4pm with entry ranging from £9.50 for adults, £27.50 for families, student and children under 16 for £5.70 and £7.60 for senior citizen.
