This is more like a twenty or twenty four foot wall (near Bethlehem), but the outward curving fence on top adds some extra adventure. Concertina is hard to pick through at ground level, so up there, at an angle, accidents are bound to happen. A thirty foot sheer concrete base takes you a long way.

Nice picture of wall. That wire fence on top DOES add to difficulty of climbing over. May be a 30’ foot wall with 4 to 5’ tall barbed wire fence on top will do the job.
