It includes a ca.1851 farmhouse, smokehouse, wagon house and horse barn, a Dutch barn built ca.1819 and expanded in 1859, a family burial ground, and 158 acres of farmland.","why_significant":"The nomination argues the farm is an outstanding, largely intact example of an early tenant farmstead on the Van Rensselaer manor, with its original buildings and agricultural setting preserved. Its Dutch barn, enlarged in 1859, is a notable surviving example. The farm also has historical significance through more than seven generations of Lainhart family ownership and continuous operation, offering insight into agricultural practices and rural life in the Capital District.","narrative":"Lainhart Farm occupies 158 acres on both sides of Lainhart Road in Guilderland, near Altamont. The complex includes a Greek Revival farmhouse of about 1851, a smokehouse, wagon house and horse barn from the same period, a family burial ground with graves dating to 1790 and 1796, and a Dutch barn built around 1819. The Dutch barn was dismantled in part and enlarged by a bay in 1859, when slate roofing was added. The farm began as a tenancy under the Van Rensselaer manor around 1768, when Michael Leonhardt settled there. His descendants kept the land through the Anti-Rent Wars, and Henry S. Lainhart obtained a quitclaim to the property in 1851. The buildings and surrounding fields remain largely intact and the farm is still worked. They document the evolution of a tenant farm over more than two centuries, and the Dutch barn preserves distinctive early timber framing.","period_of_significance":"ca.1768-1950","architect_builder":null,"architectural_style":"Mid-19th Century/Greek Revival; Dutch Colonial/Dutch Barn","criteria":["C"],"status_note":"Still a working farm: the land east of the road remains in agricultural use and the farmhouse remains a single dwelling.
