This document summarizes 10 different structures including bridges, buildings, and monuments. It describes each structure's type (e.g. frame, arch, solid), whether it is man-made, and its design purpose (e.g. to carry loads, hold people, withstand weather). The structures discussed are the Confederation Bridge, Legislature building, Saddle Dome, Great Wall of China, Eiffel Tower, Sphinx, suspension bridges, beam bridges, truss bridges, and Egyptian pyramids.
