First Harrison Gray Otis House
Museum in Massachusetts

The First Harrison Gray Otis House is a historic house museum and National Historic Landmark at 141 Cambridge Street in the West End of Boston, Massachusetts. The house, built in 1795–96, was the first of three houses built for Massachusetts politician Harrison Gray Otis to designs by Charles Bulfinch. It is notable as one of the earliest three-story brick houses that came to represent the Federal style of architecture, and its interiors show the influence of Robert Adam. The house is now the headquarters of Historic New England, a regional preservation organization, and is open year-round for tours.
Description and history
The house is the simplest of the three designed by Bulfinch for Otis. The design is said to be inspired by a William Bingham house that Bulfinch saw in 1789 in Philadelphia, which was in turned derived from a house in London. The house is three stories tall, five bays wide, with elegant string courses. Today's graceful entrance was added after 1801. Above it is a fine Palladian window, and above that a lunette. The third floor is very short; ceilings are just over 6 feet tall.

Why this record matters
The phrase “museum in Massachusetts” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Sep 5, 2026. The linked authority identifier is Q19564302. Authority coordinates are 42.361, -71.065. None of the 2 selected statements returned an explicit reference. The first chronological checks are 1795, 1789 and 1801.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
