Olympus Risen is two sets in one. First you get 8 construction props to build or expand your temple ruins. Second you get three pre-made ruins sites atop giant floating rocks, 7 separate ivy props and two iron chain props. All the props can be loaded one by one or with the load all pre-set. Each giant rock prop can be home to any structure you already own. Heck turn them upside down and you have yourself dynamic rock props.
