The story

How Loudonville came to be

From Wikipedia’s history of Loudonville.

Read it all →

The hamlet is named after John Campbell, 4th Earl of Loudoun and was originally a 19th-century summer resort for some of Albany's wealthiest residents. Loudon Road, known as Old Plank Road in the early 19th century, is lined with several historic Jeffersonian mansions. Loudonville started as a hamlet on Loudon Road (originally a plank road), at the intersection of Crumitie Road. Ireland's Corners was a separate hamlet to the north at the intersection of Loudon Road and Menand/Osborne Road, with a post office. Ireland's Corners is named for Elias H. Ireland who in 1832 bought the heavily wooded area from the Patroon, Stephen Van Rensselaer. In 1871 the post office at Ireland's Corners was renamed Loudonville.
