Green Springs National Historic Landmark District is a national historic district in Louisa County
noted for its concentration of fine rural manor houses and related buildings in an intact agricultural landscape. The district comprises 14,000 acres (5,700 ha) of fertile land, contrasting with the more typical poor soil and scrub pinelands surrounding it.
The district is located 1.5 miles (2 km) north of Interstate 64 from exit No. 136, "Zion Crossroads." The district is roughly bounded by U.S. Route 15 and Virginia Routes 22 and 613. The area is named for a natural spring noted by Thomas Jefferson as possessing "some medicinal virtue." The district features a mixture of wooded and farmed lands. Its distinguishing geological feature is the presence of a heavy clay soil that retains plant nutrients and moisture, creating an open landscape suitable for farming. The area is noted for its park-like views, particularly from U.S. Route 15.
The district was preserved following attempts by the state of Virginia to build a prison there, and after a strip mine was proposed in the area to mine clay for cat litter. The strip mine happened anyway (Google Earth maps of the area clearly show the destruction caused by the mine) but not on the scale that was intended originally and a great many significant houses and lands continue to be preserved and excluded from the development that is transforming some of the area around the district.
