Playing in the sand makes time stand still.
When the young architects let their imagination run wild, adventures begin and princes and princesses, kings and queens, and heroes and seamonsters populate the beach...
Beautiful and strange stones, some pretty shells, a couple of sticks, some leftover fishing net, and some driftwood; add a bit of imagination and an afternoon at the beach.
This is how the most amazing structures with towers, cornices, moats, and harbours are created. Eventually, a wave will come along and fill the moats and harbours with water; and sometimes a wave will be a bit bigger and you will have to start building all over again.
