The Village has been a center for movements that challenged the wider American culture, for example, its role in the gay liberation movement. The Stonewall riots were a series of spontaneous, violent demonstrations by members of the gay community against a police raid that took place in the early morning hours of June 28, 1969, at the Stonewall Inn, 53 Christopher Street. Considered together, the demonstrations are widely considered to constitute the single most important event leading to the gay liberation movement and the modern fight for LGBT rights in the United States. On June 23, 2015, the Stonewall Inn was the first landmark in New York City to be recognized by the New York City Landmarks Preservation Commission on the basis of its status in LGBT history, and on June 24, 2016, the Stonewall National Monument was named the first U.S. National Monument dedicated to the LGBTQ-rights movement. Greenwich Village contains the world's oldest gay and lesbian bookstore, Oscar Wilde Bookshop, founded in 1967, while The Lesbian, Gay, Bisexual & Transgender Community Center – best known as simply "The Center" – has occupied the former Food & Maritime Trades High School at 208 West 13th Street since 1984. In 2006, the Village was the scene of an assault involving seven lesbians and a straight man that sparked appreciable media attention, with strong statements defending both sides of the case.
