Natural Bridge, Natural limestone arch in Rockbridge County, US.

Natural Bridge is a 215-foot-high limestone arch with a 90-foot span over Cedar Creek in Rockbridge County, Virginia. Its horizontal strata form the roof of an ancient cave through which the creek once flowed. Highway 11 crosses the top, while a trail below follows the creek through the gorge.

Jefferson purchased the property from King George III in 1774 for 20 shillings and built a log cabin for guests wishing to view the formation. The site later became a popular travel destination before eventually passing into the ownership of the state of Virginia.

The Monacan people considered Natural Bridge a sacred site, believing it marked a major victory over pursuing Powhatans centuries before Europeans arrived. Today a recreation of Monacan housing stands in the state park, and the bridge remains part of the tribe's heritage.

The parking area is located near the entrance, from where paths lead down to the creek bed where you can stand directly beneath the arch. Walks range from 30 minutes to several hours, depending on whether you go only to the formation or continue onward to the waterfalls.

A stone discovered in 1927 bears the initials G. W. and surveyor marks, suggesting Washington may have measured the formation in 1750. The markings are located roughly 7 meters (23 feet) above ground level and remain visible on the rock face to this day.
