From Wikipedia:

The Montgomery-Grand-Liberty Streets Historic District was the first of two to be designated in the city of Newburgh, New York, USA. It runs along the three named north-south streets in the northeast quadrant of the city and includes 250 buildings in its 1,010 acres (4.1 km2).

Much of the district’s historical character comes from its historic homes, dating to the 19th century. Many were built by local industrialists to take advantage of the views over the Hudson River available from the neighborhood. Some incorporated groundbreaking design trends pioneered by Newburgh native Andrew Jackson Downing, making the area important in architectural history. It was thus added to the National Register of Historic Places in 1973. Three contributing properties — the David Crawford House, Old Town Cemetery, and Newburgh’s main post office — are separately listed on the Register, and one, the Dutch Reformed Church, has been recognized as a National Historic Landmark.
