US Post Office-Williamstown Main
Also known as: Williamstown Main Post Office
Why it's listed
Built in 1932, this post office on Spring Street in Williamstown sits in the town's commercial section, among two and three story buildings from the mid to late 19th century. The building is brick laid in Flemish bond on a granite base with a marble stringcourse. Broad granite steps lead to a pedimented portico whose columns are each cut from a single piece of veined marble. Marble also appears in the window trim, the entrance surround and the parapet rail. Inside, the lobby keeps its quarry tile floor with marble borders, grey veined marble wainscot, classical cornice and marble basement staircase with wrought iron balusters. Only the vestibule, entrance doors and ceiling lights are new. The building was constructed as post office construction expanded during the early Depression years. It was recognized for the unusual amount of architectural detail applied to a standard plan, and for its role as a daily meeting place for the town and its college community.
Significance in brief: Built in the early years of the Depression when post office construction increased, the building is unusual for the attention given to its exterior. Its abundant architectural detail on a standard plan makes it an important building in the community. It also serves as a common place of business and interaction for the town and its diverse college community.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
