The Calvin Coolidge Homestead District at Plymouth Notch preserves many of the historic buildings that Coolidge knew in his youth: his birthplace, his boyhood home, the church that he attended, the homes of relatives and family friends, and the hall above his father’s old store, which he used as his office during the summer of 1924 and others.

The Calvin Coolidge Presidential Foundation is the official foundation dedicated to preserving the legacy and advancing the values of America’s thirtieth president. The virtual library contains speeches, press conferences, veto messages, proclamations, and quotations.
