Brattle Street in Cambridge, Massachusetts, called the "King's Highway" or "Tory Row" before the American Revolutionary War, is the site of many buildings of historic interest, including the modernist glass-and-concrete building that housed the Design Research store, and a Georgian mansion where George Washington and Henry Wadsworth Longfellow both lived (though at different times.) Samuel Atkins Eliot, writing in 1913 about the seven Colonial mansions of Brattle Street's "Tory Row," called the area "not only one of the most beautiful but also one of the most historic streets in America." "As a fashionable address it is doubtful if any other residential street in this country has enjoyed such long and uninterrupted prestige."
Even before the settlement known as "Newe Towne" was planted on the site of the modern Cambridge, at the first good Charles River crossing west of Boston, the path or trail from Charlestown to Watertown ran past the site of the current Harvard Square and westward along much of what is now Brattle Street.
In early 17th century Newe Towne, according to historian John Fiske, "On the north side of Braintree Street, opposite Dunster, and thence eastward about as far as opposite the site of Linden, stood a row of six houses, and at their back was the ancient forest. Through this forest ran the trail or path from Charlestown to Watertown, nearly coinciding with the crooked line Kirkland - Mason - Brattle - Elmwood - Mount Auburn; this was the first highway from the seaboard into the inland country." Where the current Ash Street intersects the current Brattle Street stood Newe Towne's West Gate, a palisaded fence to keep cattle out of the town.
During the 18th century, seven mansions were built along the main road to Watertown (which included not only the modern Brattle Street but also what is now Elmwood Avenue). Because many of their owners were Loyalists during the American Revolution, these houses got the nickname "Tory Row". During and after the Revolution, many were confiscated by George Washington's army. Some of these were, however, later restored to the families of their former owners.
