Basalt paving on the Via Appia (Appian Way), the main road linking Ancient Rome with its main cities. Basalt is an igneous rock formed when lava cools. It is tough and resistant to erosion, making it an ideal material for roads. The Via Appie was started in 312BC and extended many times. Photographed by the Tomb of Cecilia Metella, Italy.
