The Portland Breakwater lighthouse had a strange attachment mounted on the outside of the tower that extended from the gallery to below the granite base. Can anyone guess the purpose of this attachment.

Good question Dave, and one to which I don't have an answer. I thought it could be a day mark or perhaps a conduit for electricity cables. I did find an interesting web site with some history of the light and its keepers.

Things were tough in those days.

Kevin --- The purpose of this appendage was not directly mentioned in the text on the web site you posted. However, the reason for its existance and function was discussed in the text and can be seen in one of the photos.

I scanned the text previously and missed the bit about the shaft. How weird.

I misread the article. I thought it was something to do with waste disposal from the little room/s.

It served to contain the 1000 pounder clockwork weight but from the web site you posted it appears to have first served the clockwork weight for the light when changed from fixed to flashing. This photo from that site pre-dates the 1000 pound bell.

Thanks.
That tall ship in the background has an interesting set of sails and masts.

Kevin --- The tall ship in this photo was a 4-mast schooner that was designed to haul bulk cargo from port to port. Being schooner rigged it was easy to manuver in and out of relatively confined channels as opposed to full rigged ship with square sails. A schooner requires far fewer crew members than a full rigged ship and will sail much closer into head winds, "jam the wind", thus the term "windjammer. The largest of these was the Lawson---395 ft with 43,000 sq.ft. sail, masts 156 ft. above deck. In fact it was too big.

mylights --- Wayne Wheeler does a great job with his renditions of the history of various lighthouses. He is thorough with his research. Only a very few of his stories have been made available on the internet.
