Full moon at the spring equinox in 2021 meant one thing on the North Wales coast- high tides - the highest tides of the year in fact.
This is the only time in the year (apart from the autumn equinox, that is) that the sea manages to rise across the acres of silted up salt marsh on the river Dee estuary and touch the walls of Flint castle.
This medieval ruin, built by King Edward the First to keep the unruly welsh in order, was right next to the open water when it was built back in the twelfth century, but now it's only a couple of times a year that the castle walls get wet.
And I was on hand to enjoy and film the spectacle over the course of an hour or so, watching as the undulating marsh surrounding the castle slowly filled with water, creating this lovely time lapse in the calm and sunny conditions.
I can think of worse ways of whiling away a morning!
