Briar thorn wall

Repeating 6 m module of a fortress wall grown from giant brambles: 8 m tall and 3.2 m thick, braided thorn cables and rising stems bristling with thorns, a 2.8 m walk of flattened stems on top at 7 m with thorn spikes along both edges. Tiles on a spline between bastions and gates. Living green-brown bramble with straw-coloured thorns and red roses.
