These concrete pylons date to WWII and were used as supports for elecricity and communications cabling to the signal and watch house on Crammon Island. They also effectively stop any low-draft boats passing through there even at the highest tides. At low tide they are completely exposed and you can walk to the island.
Still part of the B&W UK Series, even if it's technically not a street scene as such.
