The Ames Free Library first opened its doors in 1883. Under the terms of the will of Oliver Ames II, $50,000, in trust, was left for the construction and support of a library for the benefit of the inhabitants Easton. The library was designed by Henry Hobson Richardson in 1877 and opened in 1883, becoming one of the finest public libraries in the region. The library is built of Milford granite with the same Longmeadow trim used on his famous Trinity Church in Boston. The very low cavernous arch over the doorway was used here by Richardson for the first time and became one of the most prominent and widely imitated characteristics of his style.
