The wooden tower is 36 feet high and a standing platform at 30 feet is surrounded by a thorny brush that has been fastened there. The tower is not manned, but a single person could probably hold it for a considerable time. The thorny ring gives hampers climbers and is dense enough to even protect against missiles. An unhindered climber would take 5 minutes to climb the platform without being wounded. A climber is helpless against attacks from the platform. A long ladder (or a similar construction) would be of use.
