As you pass signs for Flint and Holywell, you can see the Moey-y-Parc Transmitting Station.
The Moel-y-Parc transmitting station is situated on Moel-y-Parc, a hill and country park in north-east Wales at the northern end of the Clwydian range, close to the town of Caerwys and several kilometres north-east of Denbigh. It was built in 1962/1963 by the Independent Broadcasting Authority to bring ITV television to North Wales and it has been on the air since 1963. Its original height of 229 m made it the tallest structure in North Wales and it stands on land that is itself about 335 m above sea level. In 1965, VHF television transmissions from the BBC commenced from the site. With the addition of the UHF aerials in 1969, the mast height increased to 235 m high.
