An example of a temple made of Roman concrete in the 1st century BC is the Temple of Vesta in Tivoli, Italy. The concrete was made of nothing more than rubble and mortar.

Reconstruction of a 10.4 m (34 ft) high Roman Polyspastos in Germany. The ancient Romans were famous for their advanced engineering accomplishments. Technology for bringing running water into cities was developed in the east, [clarification needed] but transformed by the Romans into a technology inconceivable in Greece.
