Cascata delle Marmore, Ancient Roman waterfall in Terni, Italy
Cascata delle Marmore is a waterfall in Terni, Italy, created through a system of Roman canals that directs the Velino River over three drops totaling 165 meters (541 feet) into the Nera River below. The water is controlled by modern gates, so the full flow becomes visible only at scheduled times.
Roman consul Manius Curius Dentatus ordered a canal dug in 271 BC to divert the Velino and drain marshes that caused disease. Later engineers expanded the canal system over the centuries, and eventually the water was harnessed for power generation as well.
The Latin name refers to the white limestone deposits that have formed on the rock faces over centuries, giving the falling water a milky appearance. Visitors follow several walking paths that lead to different viewpoints, allowing direct contact with the spray.
Opening times for the full water flow change with the season, so visitors should check daily schedules in advance before traveling. Several walking paths lead to upper and lower viewpoints, with sturdy footwear advisable due to wet surfaces and stairs.
The flowing water creates rainbows in the spray when sunlight hits it, drawing photographers at certain times of day. The gates open with a clearly audible signal, allowing visitors to watch the sudden surge in flow.
