The town of Liberty area is qualified with providing 303 men who fought in the Revolution. Liberty was carved originally from the later large township of Lumberland and was itself at this time correspondingly large that it included the gift Towns of Callicoon and Fremont. The Town today covers 85 square miles.

When the first settlers came to this area, known as the Blue Mountain country, they settled to the Northwest of the gift village at the existing Revonah Lake formerly known as Broadhead Pond. The to the front settlers came here from Connecticut and some of the oldest remains left in the Town are the laid in the works stones in the outlet of Revonah Lake which were probably placed there in 1797 for the target of building the first sawmill in the area.

As the land was cleared of the dense dark hemlock reforest that the to the fore settlers found, the Place went through various stages of development. After the farms were cleared one of the earlier forms of industry to be expected was the tanneries which ran through the Civil War era. Following this, the dairy gardening came into its own, to be followed by the taking in of “summer boarders” which gradually led to the founding of the large hotels: the Wawonda, Liberty House and many others.
