- For more than 300 years Portland Bill's famous lighthouses have warned ships of this treacherous coast. 1716 to 2020. This unique documentary includes nostalgic footage of the old revolving beams. Listen to the mind-blowing blast of the old diaphone foghorn, which could be heard for miles even inland. Everything changed in 2020. This 47-minute video includes unique footage. This is a fascinating story of the iconic and famous lighthouses of the Isle of Portland. Follow their evolving - often world-beating - technology, from the crude coal fires of 1716 to the advanced LED lamps of the 21st century.

Few realise how much work is involved in researching and producing a programme such as this. My hat is off to you sir!
Amazing and well put together. The old foghorn recordings nearly brought tears to my eyes, memories of better times.
The sound many of us grew up with, it should never have been removed but kept for posterity and used on occasions and events
Very interesting !
Wonderful presentation. It is sad to see so many changes in lighthouses. I really miss the fog horns as here in Ireland, all fog signals were discontinued in 2011. Thankfully due to several protests, Irish Lights have stopped removing Fresnel lenses from onshore lighthouses to retain the heritage of the lighthouses. Once the mercury has been removed, they use ball bearings in order for the lens to rotate.
Thanks, very interesting to know the situation in Ireland. I wouldn't be surprised if the Chance Brothers made the Fresnel optics for your lighthouses too. They supplied them all over the world.
Well done Stuart a truly excellent video and evoked many happy memories of seeing the old light and foghorn many years of coming down to Weymouth and Portland on holiday the new one is very different but pretty in it’s own way and of course a useful aid to all at sea ironically the works of Chance Bros is about three miles from where I live and the factory exists still albeit in a run down state they were exceptional engineers and the achievements they created made so much difference I am so glad the old light has survived
Hi Daniel. I'm so pleased that you enjoyed this one (incidentally an earlier version had several thousand viewings). I have seen a video about the Chance Bros works, what a sad end to a fantastic, world-leading business. Hopefully, something worthwhile will get developed on the site. Thanks for your kind comments.
@@StuartMorris7 you are very welcome wow that is incredible all those comments! Yes it is a terrible shame to see chance glassworks now when you pass it the council have been looking at changing it into a museum for years and it still remains to happen as yet
@@danielrussell446 Well I hope something transpires to do justice to the history of the site.
Stuart, super video. Can you tell me how the number of flashes reduced/increased from one to four while the lens assembly rotated? At 27 min 28 secs clearly we only see three flashes. From Mupe Bay we could only see two flashes, and Abbotsbury only one. I have asked guides many times - but no-one seems to know. All LED now so four on its full arc. Were Chance staggeringly clever? The bearings where the flashes reduced/increased were defined on all the old Admiralty Charts - as a navigational bonus. One flash and you are heading for rocks!
A good question. I think it's due to the side lenses being half-circles rather than full circles, See close-up at 46m 24s. Chance Bros certainly did know their science.
I didn't know about the 'missing' flashes. It would be good if someone with expert knowledge of optics and lenses could explain it.
