This particular one was a beauty, we kept on thinking we were finished, but the water was nowhere near destroying it so we had to just keep on building.
Trent would have spent a solid five hours there, but I left once to get drinks and once to pick up our washing.
In the end it was still going to be hours until the tide came up high enough to reach it so, despite our fears of dogs and children as well as errant trucks and motor bikes destroying all the hard work, we abandoned the masterpiece to the mercy of the elements.
But when we came back in the morning it was still intact. The water had made it to the outer defences, but the main wall was still intact. A marvel of modern engineering.
The mistress unfortunately didn't make it-someone stepped on her head, the only human interference with the whole thing.
We stayed and watched the first wave breach the wall and when we came back from a stroll up the beach it had been washed away entirely, with only a pile of shells and stones to remind us of it's former splendour.
