The story behind this video

During the 13th century Edward the First built a series of castles along the welsh coast in order to impose his rule over the fractious natives.

The most northerly of these is Flint castle on the estuary of the river Dee, featured in this time lapse video.

When the castle was originally built the sea came right up to the walls, providing both defense and a means of resupply in the event of a siege.

But over the centuries the river Dee silted up, leaving Flint castle high and dry for most of the year.

However, every now and then when there's a particularly high spring tide the sea manages to briefly reclaim the land it lost, returning once again to wet the stones at the base of the castle.

Such was the case on this day in late September, when my wife Liz and I positioned ourselves on the earth berm overlooking the salyt marsh in front of the castle to watch and film as the tide came in.

The weather was quite frisky that day, with clouds racing by overhead casting patches of sunlight and shadow over the rapidly disappearing marsh below.

Then a brief shower arrived, creating a vivid rainbow over the castle just as the tide reached its highest point.

Once the tide turned and started going out again we re-postioned ourselves and filmed another time lapse sequence, Flint Tide Timelapse #2, showing the marsh grasses re-emerging from under the sea.
