The main U.S. Post Office in Newburgh, New York is located at 215-217 Liberty Street two blocks north of Broadway. It serves the 12550 ZIP Code, which covers the city and nearby areas of the Town of Newburgh. There is a branch station located on Broadway in the western neighborhood of the city. The building itself is a two-story brick structure built in the early 1930s. It was designed under the supervision of James Wetmore, supervising architect for the Treasury Department at the time, and takes a Colonial Revival style.It was added to the National Register of Historic Places in 1989; it is also a contributing property to the Montgomery-Grand-Liberty Streets Historic District.

The Newburgh Free Library serves as the public library for the residents of the Newburgh Enlarged City School District. The Newburgh Free Library is the Central Reference Library for the Ramapo-Catskill Library System and is a member of the Newburgh Library Collaborative. In fiscal year 2010, the Newburgh Free Library had a collection of over 300,000 print and electronic resources.

The Dutch Reformed Church is one of the most prominent architectural landmarks in Newburgh, New York. It was designed by Alexander Jackson Davis in 1835 in the Greek Revival style just after the dissolution of his partnership with Ithiel Town. It is his only surviving church in that style and is considered to be his latest building still standing that largely reflects his original vision. The church stands at 132 Grand Street, just north of the Newburgh Free Library. Its historical importance comes from not just over a century of use as church, but its centrality in the struggle by modern preservationists to save and restore the city's many landmark buildings. Today it is a National Historic Landmark. It was almost razed in the late 1960s, and even today is far from completely restored. The property was added to the National Register of Historic Places in 1970, aiding its rescue from demolition.

The City Club, known also as the William Culbert House, is a historic ruin at the corner of Grand and 2nd Streets in Newburgh, New York. Designed in the early 1850s by Calvert Vaux and Andrew Jackson Downing, the house survived Urban Renewal efforts but succumbed to fire in 1981. Plans have been made since its destruction to reconstruct the interior, a project often paired with restoration of the nearby Dutch Reformed Church, but none have ever been executed. The house appears in Vaux's most celebrated work, Villas and Cottages (1857) as Design No. 22. It is one of the earliest Second Empire houses in the United States, designed just after Detlef Lienau's now lost Hart M. Shiff House (1850) and the earlier Edward Deacon House in Boston's South End. For a brief time in the late 1970s, the former City Club housed the offices of restorer Brian Thompson. Due to its centralized location, it has become a symbol of the restoration movement in Newburgh, also representing the city's decay.

The Halsey Stevens House is a historic house located at 182 Grand Street in Newburgh, New York. It is one of the first residences designed by the architects Calvert Vaux and Frederick Clarke Withers after the death of their mentor Andrew Jackson Downing the previous year. Listed as part of the Montgomery—Grand—Liberty Streets Historic District in Newburgh, the house has been well-preserved and demonstrates how both worked with Gothic Revival and Italianate styles. Halsey R. Stevens, their client, was a lumber dealer and Biblical scholar.

The Church of the Corner Stone was a Reformed Episcopal congregation in Newburgh, New York, formed nearly 2 years after a split from the Protestant Episcopal Church in 1873.

The David Crawford House is a historic house located at 189 Montgomery Street in Newburgh, Orange County, New York. It currently serves as a museum, archive and headquarters for the Historical Society of Newburgh Bay and The Highlands.

The Montgomery–Grand–Liberty Streets historic district was the first of two to be designated in the city of Newburgh, New York, United States. 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). The later East End Historic District (Newburgh, New York) is nearby. 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.

The Old Town Cemetery is located in the city of Newburgh, New York, behind Calvary Presbyterian Church on South Street. It was established in 1713 by Palatine German refugees from the Rhineland-Palatinate who were transported from England in 1710 and settled on the site of the present city of Newburgh. The cemetery is within a section of the city known as the Glebe, a 500-acre (2 km2) grant made by Queen Anne to provide for a schoolmaster and clergyman for these German families. A church built by the Palatines was located on the western edge of the site, on what is now Liberty Street. As the Old Town Cemetery and Palatine Church Site, it was listed as a historic district on the National Register of Historic Places in 2000. It is also a contributing element in the larger Montgomery-Grand-Liberty Streets Historic District.There are an estimated 1,700 burials in the cemetery, although there may at one time have been 2,500. Thirteen hundred headstones survive today; the earliest date of death still legible is 1759. Among the noteworthy persons are congressmen Jonathan Fisk and Thomas McKissock. The mausoleum of ship Capt. Henry Robinson, his wife Ann Buchan Robinson, and their two daughters, Sarah Robinson and Mary Robinson Benkard is architecturally distinctive. It was built in 1853, possibly by Alexander Jackson Davis, whose most notable work in Newburgh, the Dutch Reformed Church, stands a few blocks away. It is believed to be the only Egyptian Revival tomb to feature both a mastaba and a pyramid. It was overgrown and fell into disrepair until a 1999 restoration.An interesting memorial marker here is the one for Archibald Wiseman and two of his young children by his wife, Susan Clyde, located at gravesite 1-140. Somewhat of a mystery is the inscription on the marker that reports that he died at sea on May 9, 1853. His widow Susan remarried in 1860 to a James McCord, a leather tanner and apparently unrelated to the McCord family of brush manufacturers in Newburgh, and she and McCord are last recorded in the 1880 Census at the home of her son, David Clyde Wiseman (who suffered from 'consumption') and his daughter Mary, who married in about 1869. Mary was the only daughter of James McCord by an earlier marriage. Susan and James' later fate after 1880 is unknown as of June 2011. In 1803 New York amended the law governing the Glebe, and later an Old Town Cemetery Commission was created by the city. It consists of five members, three of them serving ex officio: the city's mayor, the local superintendent of schools and the pastor of Calvary Presbyterian Church. The other two members are appointed by the city council. Currently those are John McCormick and Gerardo Sanchez, whose company restored the Robinson Mausoleum.

The Eugene A. Brewster House is a historic house located at 264 Grand Street in Newburgh, New York. Built in 1865, the year Newburgh incorporated as a city, it was designed by English immigrant architect Frederick Clarke Withers for attorney Eugene Augustus Brewster.

The James Walker Fowler House was a historic house in Newburgh, New York, occupied in the mid-19th century by Judge James Walker Fowler (1820—1905). After Fowler's death, the house passed through two owners before becoming the residence of Captain Thomas S. Marvel, a shipyard owner at the turn of the 20th century. In the 1970s, the house was demolished as part of the city's Urban Renewal efforts.
