Built in 1808 and named after the historian who lived there in the mid-1800s, this mansion is not a Charles Bulfinch creation, but rather one from the hand of Asher Benjamin, who would end his career working in the Greek Revival style.

This is the federal work everyone remembers Benjamin for, however, though through the pilasters and the Doric columns you can almost see a more vigorous approach yearning to show itself.

It's now a museum that the National Society of the Colonial Dames of America runs. (Bonus federal: Benjamin also designed 54 Beacon.)

Asher Benjamin designed this building, which went up in 1806 and remains the oldest African-American church building in the U.S.

Not surprisingly, the building served as a hotbed of abolitionism in the early 1800s, and became a synagogue in the 20th century.

The Museum of African American History purchased it in the 1970s, and it remains a part of that institution.

Charles Bulfinch designed this mansion at 141 Cambridge Street for Harrison Gray Otis, a congressman, senator and Boston mayor (whose political affiliation was—what else?—Federalist).

It was completed in 1796, and its flat facade positively drips of the architecture.

It was later used as a clinic and a middle-class boarding house; and is now a museum.

The State House was finished in early 1798 and built on a cow pasture John Hancock once owned. Charles Bulfinch designed this building as well.

Its construction signified Boston's permanence as the capital of the commonwealth.

A builder named Thomas Fletcher constructed this four-story rowhouse in 1808. Various owners renovated it throughout the 19th century, including painter Chester Harding, who lived there in the late 1820s.

The Unitarian Church Association acquired 16 Beacon Street in the 1920s, and adapted the house for use as an office. In 1963, the Boston Bar Association moved in, and renovated it some more (the group still owns the property).

Yet its facade especially retains the trappings of that federal style.

Originally Georgian in design, the market and assembly hall went up in the early 1740s and had to be rebuilt 20 years later after a fire destroyed most of it. (Money from the slave trade underwrote Faneuil’s construction both times.)

Charles Bulfinch designed the federal-style expansion of Faneuil Hall at the start of the 19th century.
