There was generally little support for the preservation movement until World War II. Structures such as the City Hall Post Office and Courthouse, Madison Square Presbyterian Church (1906), and Madison Square Garden (1890) were demolished if they had fallen out of architectural favor. Others, such as St. John's Chapel, were destroyed in spite of support for preservation. By the 1950s, there was growing support for preservation of architecturally significant structures. For example, a 1954 study found approximately two hundred structures that could potentially be preserved. At the same time, older structures, especially those constructed before World War I, were being perceived as an impediment to development. The demolition of Pennsylvania Station between 1963 and 1966, in spite of widespread outcry, is cited as a catalyst for the architectural preservation movement in the United States, particularly in New York City.
