The Ammendale Normal Institute is a U.S. historic location in Beltsville, Maryland.

[2] Construction of the main building began in 1883 and was completed in 1884 with Thomas C. Kennedy as the leading architect.

Ammendale was one of many historical buildings in the region with valuable real estate that was developed after a fire set to the structure, including Troy Hill (1990), Avondale Mill (1991), St. Mary's College (1997), Henryton State Hospital (2007), (2011)[6] In 2014, NAI Michael placed 8 acres containing the foundation of the Normal Institute and the remaining historic brick barn up for sale.

It is a front-gabled brick chapel with ornate Queen Anne detail.

Jigsawn vergeboards adorn the eaves of the principal gable front, the gothic-arch windows are filled with stained glass, and the interior walls and ceilings are sheathed with pressed tin in a pattern of fleurs-de-lis, palmettes, and a rich, multicourse cornice.
