An amble along the Ancient Appian Way (Appia Antica) is actually a leap back in time to understand the daily life of Rome the Imperial and Republican Rome. Appia Antica is also known as "Regina Viarum," and is composed of slabs of lavic rock (basalt). Originally built as a military road, it later became an important commercial artery connecting Rome to its Imperial Provinces. Numerous funerary monuments stand along the Appia Antica; the monuments belonged to Ancient Rome's most important families, and were symbols of pride and, in their culture, of guaranteed eternity. One example of these is the impressive Mausoleum of Cecilia Metella. There are also remains of suburban villas like Villa dei Quintili, which served both agricultural and residential uses.
