Public Square Historic District (Boundary Increase)
Why it's listed
Public Square Historic District covers the heart of downtown Watertown, New York. It includes 66 properties: 64 buildings, a monument and the village green itself, which was created in 1805 and landscaped in 1855. Most buildings are three- to four-story attached masonry rows, chiefly brick, built between the late 1840s and early 1930s in styles such as Italianate, Romanesque Revival, Neoclassical, Commercial and Art Deco. Fires in 1848 and 1849 and in the years after destroyed nearly the whole business district, and the city rebuilt it in the third quarter of the nineteenth century with finely crafted masonry structures, financed by prosperity from steam engine, textile and paper industries. Landmarks include the Paddock Arcade, the Marble Block, the Soldiers' and Sailors' Monument and a cast-iron fountain from 1869. Similar scale, form and materials give the streets a cohesive look, and the district marks Watertown's long standing as a regional commercial center.
Significance in brief: The district holds the city's only concentration of intact historic commercial architecture, largely rebuilt in the 1850s-1870s after fires destroyed the earlier downtown. Its buildings, dating from the late 1840s to the early 1930s, show a range of popular American styles and reflect Watertown's role as the commercial and industrial center of the region.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
