Brick piers frame the slightly recessed entry, which has slender Tuscan columns on either side, supporting an entablature with a half-round wagon wheel window.

The interior of the building features richly detailed woodwork, particularly in the paneled entry hall.

A stained glass window decorates the central section, with reading rooms in the flanking wings.

[2] The Wilton Free Public Library was established in 1901 by petition of the town residents, and originally housed in one of the downtown commercial buildings.

In 1914 the town received a bequest from the estate of Agnes I. Goodspeed, supplemented by additional donations by her sons, for the construction of this library building, which was dedicated in October 1916.
