A fence-hedge hybrid, not designed to deter animals.
A wild and deep hedge, minimally weaved. Kept together with stout vertical hazel poles, and clamped down with semi-circles of bent wood laid horizontally over the mass. Impenetrable to larger beasts while providing a shelter to smaller ones.
And finally, as if heaven-sent, a piece of hand-made fence disguised as a gate, which doesn't open and leads nowhere and serves no purpose. It's a lovely thing.
