A wooden trebuchet, a siege weapon used to hurl projectiles, stands in front of a stone wall. The trebuchet is made of large, sturdy beams of wood held together with ropes and metal brackets. It has a large arm that swings back and forth, powered by a counterweight.  The wall is made of rough, uneven stones and has two small windows with iron cross shapes. Two white pipes run down the wall, each with a small rectangular structure at the top.
