Stone walls were often the result of clearing the land of rocks so that the land would be more fertile. The rockier the land of the area the more walls there are, and the smaller the fields. The building of them was considered an art form – not everyone could build a functional and beautiful wall, and those who could were respected. Walls as demarkation was of course necessary, but they were never built so that they couldn’t be crossed. They’re a great windbreak, or a prop t lean against for a wee snooze in the sun, and this one has become a support for a blazing gorse bush.
