Bellows Falls is unique in having examples of homes of just about every architectural style in New England—including Federal, Greek Revival, Gothic Revival, Italianate, Second Empire, Stick, Shingle, Queen Anne, Colonial Revival, Dutch Colonial Revival—and pretty stellar examples at that.
The town produces a self-guided walking tour to the Bellows Falls Historic District (802/463-3964, www.rockbf.org [1]). Highlights include the Second Empire Wyman & Almira Flint House Masonic Temple (61 Westminster St.) and the curious Greek Revival/Queen Anne-hybrid Babbitt Tenement House (11 South St.).
Homes are private and not open for tours, but a walking tour of their exteriors is a more than pleasant way to pass an afternoon.
