Pondweed bubbles, Raglan Castle moat, Wales, UK in the afternoon on 16th July 2022 – by Paul Ridout

“It was a blazingly hot afternoon and the sunshine on the pondweed in the moat was generating bubbles that were popping all around as I sat in a “Watergate” at the foot of the keep, looking across to the niches which had, until the “English” Civil War, contained statues of Roman emperors.  You can hear pied wagtails, visitors to the castle, distant traffic on the A449 and maybe even a dragonfly.”
