Designed by a prominent architect, Willard T. Sears, the Lincoln Building at Lincoln and Essex streets, is a handsome example of a late 19th century mercantile structure consisting of stores, office & loft space, serving as an important visual anchor the almost uninterrupted neighborhood of the Leather District of Boston. The building is the second of its name, with the first Lincoln Building succumbing to the Lincoln Street Fire of 1893, which started as a small fire in a restroom of a toy wholesaler, eventually spreading to a storage room full of fireworks, which exploded, eventually killing at least five, and forced many others to jump from buildings to seek safety. The replacement building is Renaissance Revival in style with a stone base and classically decorated facades. The recessed entrances set within arches and the series of columned bays at the ground floor are truly special. The building was long-occupied by leather dealers and companies, but was converted to residential use in 2006 with condos on the upper floors and retail spaces on the street.
