Alexander Graham Bell's tetrahedral tower was built as a lookout point over the estate, and it also demonstrated the use of the tetrahedron as a way to make a structure remarkably strong. It was a three-legged iron tower which was seventy-five feet high. The tower which was composed of many smaller cells was built on the ground and then raised to an upright position.
