Disordered piling
From Infogalactic: the planetary knowledge core
Disordered piling (乱石積 ransekizumi?) is a Japanese wall-building technique consisting of large number of small stones packed tightly together.[1] It was used in some Japanese castle walls to create a wall that was difficult to climb. As it became more sophisticated it evolved into a technique known as burdock piling.[2]
