I've just watched the first programme in a very interesting new TV series on BBC 1 Wales tonight at 1735, called "Iolo's Welsh Seas".
It showed the windfarms on the Constable Bank, lobster pot fishing off the Orme, and diving on the wreck of HMS "Conway" in the Swellies between the bridges in the Menai Straits and some great aerial views of St. Cwyfan's Church and Llanddwyn Island. If you missed it and want to see it I imagine you will be able to catch it on I-player.
