as pottery shards and "projectile points". Other excavations have found artifacts from the 17th and 18th centuries, including war artifacts up to below ground level. Together, the park and the Cloisters were listed as an historic district on the National Register of Historic Places in 1978. The Cloisters had been designated a New York City landmark in 1974, while Fort Tryon Park was designated a scenic landmark in 1983. Public use and perception In 2012, an examination of tweets and emoticons determined that Fort Tryon Park was "the happiest spot in Manhattan". Because of its secluded location, the park is frequently used for wedding photographs and ceremonies, though the park remains open to the public while these events take place. On the other hand, Fort Tryon Park has historically been used as a location for sexual intercourse due to this seclusion, and in some years, New York City Police Department officers would issue summons once a week. However, since the 2000s and 2010s, summons for public intercourse have decreased greatly. The Fort Tryon Park Trust helps fund programs for all ages like yoga and tai chi classes, live outdoor concerts, and bird walks. The Trust also supports local artists' displays within the park, facilitated by the New York City Parks Temporary Public Art Program. Fort Tryon Park also hosts several annual events. The Medieval Festival, an annual event that has taken place at the park since 1983, typically takes place at the end of September and draws an average of 60,000 people. Additionally, Open House New York hosts the Annual Open House New York Weekend each October, collaborating with the Fort Tryon Park Trust to give tours of the Billings cottage and the Heather Garden. Other annual events include the "Shearing of the Heather" in April, the "Urban Wildlife Festival", the remembrance of the Battle of Fort Washington in November, the Scandia Symphony concert in June, the Harvest Festival in October, and "A Toast to Fort Tryon" each summer. In media Several films contain footage shot in Fort Tryon Park or the Cloisters. In 1948, director Maya Deren used the Cloisters' ramparts as a backdrop for her experimental film Meditation on Violence. The same year, the film Portrait of Jennie used the Cloisters as the location for a convent school. Additionally, two scenes in the 1968 film Coogan's Bluff were filmed in Fort Tryon Park: a shoot-out at the Cloisters
