Hyde Hall is a large Federal and Greek Revival country house on the eastern shore of Otsego Lake, within Glimmerglass State Park, constructed between 1817 and 1835 for George Clarke, a wealthy landowner of English origins. It is considered one of the most significant Federal-period domestic buildings in the United States, representing an unusually intact example of an early 19th-century American gentleman's estate.
The house is open for guided tours in summer and early fall. The grounds include original farm outbuildings, a formal garden in early stages of restoration, and direct access to the Otsego Lake shoreline. From Hyde Hall, a footbridge — the oldest surviving cast-iron bridge in the United States, dating from 1825 — crosses a small creek. The drive from Cooperstown along the eastern shore of Otsego Lake to Hyde Hall is one of the more scenic roads in the Catskills.
