Newburgh is the location of numerous preserved landmarks, including Washington's Headquarters, the David Crawford House, New York State Armory, the Dutch Reformed Church, and Newburgh Colored Burial Ground. George Washington and Franklin Delano Roosevelt had ties to the city; Ulysses S. Grant, Robert Kennedy, and Theodore Roosevelt also visited, the latter delivering a famous speech at a nearby shipyard. The city served as a planning ground for the Gothic Revival architectural movement in America, headed by native Andrew Jackson Downing with English architects Calvert Vaux and Frederick Clarke Withers.
