Blackacre Nature Preserve and Historic Homestead is a 271-acre (1.10 km2) nature preserve and historic homestead in Louisville, Kentucky. The preserve features rolling fields, streams, forests, and a homestead dating back to the 18th century. For visitors, the preserve features several farm animals including horses, goats, and cows, hiking trails, and a visitor's center in the 1844-built Presley Tyler home. The farmhouse is open to the public on Sundays, 1:00 p.m. - 5:00 p.m., from March through November. The preserve and homestead are open every day - weekdays from 3 p.m. to dusk, and on weekends from dawn to dusk. Since 1981, it has been used by the Jefferson County Public Schools as the site of a continuing environmental education program. About 10,000 students visit the outdoor classroom each year.
The preserve was created in 1979 when the land was given to the Kentucky State Nature Preserves Commission by Judge Macauley and Mrs. Emilie Smith creating the first nature preserve in the Commonwealth's system. The Blackacre Conservancy, founded in 1983, operates the historic homestead and conducts cultural and historical programs while the Commission retains ownership of the preserve and manages its natural resources.
Blackacre is part of the old Moses Tyler farm, several original farm buildings remain, including the 1844 Presley Tyler home, an Appalachian-style barn and a reconstructed stone spring house. The entire 600-acre (2.4 km2) settlement has been named a national historic rural settlement.
