The Pilsbury Block is an historic commercial building at 200-210 Lisbon Street in Lewiston, Maine. The block was built in 1870, and is a late example of Italianate architecture, exhibiting some Romanesque details. The building was added to the National Register of Historic Places in 1983.^[1]

The Pilsbury Block is located on Lisbon Street, Lewiston's principal commercial thoroughfare, at the northeast corner with Pine Street. It is a three-story masonry structure with a narrow rounded bay at the street corner. The upper floors are divided into large bays, five facing Pine Street and six facing Lisbon, each set in a recessed arched panel. There are paired windows in each panel, set in round-arch openings on the third floor and segmented-arch openings on the second. The ground floor storefronts are set in groups of segmented-arch or flat-topped segments of stone, with either display windows or entrances topped by transom windows. The building is capped by a corbelled brickwork cornice.^[2]

The oldest portion of the building, the corner section, was built in 1870 for George H. Pilsbury by Jesse T. Stevens, a local engineer. The architect may have been William H. Stevens, who was closely associated with Pilsbury in the Franklin Company^[3] and the Lewiston Institution for Savings (later the Peoples' Savings Bank).^[4] In 1873 it was enlarged by the addition of three bays on Lisbon Street. The addition is known to have been designed by Stevens, now practicing as Fassett & Stevens. The building is one of Lewiston's oldest surviving commercial buildings, and a rare example of transitional Italianate-Romanesque architecture.^[2]

The Pilsbury Block is now part of Lewiston Public Library.^[5]
