particular, parks were designed to incorporate landscapes whose elements were related to each other. A New York City icon, Central Park is the most filmed location in the world. A December 2017 report found that 231 movies had used it for on-location shoots, more than the 160 movies that had filmed in Greenwich Village or the 99 movies that had filmed in Times Square. Some of the movies filmed at Central Park, such as the 1993 film The Age of Innocence, reflect ideals of the past. Other films, including The Fisher King (1991), Marathon Man (1976), The Out of Towners (1970), and Home Alone 2: Lost in New York (1992), use the park for dramatic conflict scenes. Central Park has been used in romance films such as Maid in Manhattan (2002), 13 Going on 30 (2004) or Hitch (2005), and fantasy live-action/animated films such as Enchanted (2007). In 2009, an estimated 4,000 days of film shoots were hosted, or an average of more than ten film shoots per day, accounting for $135.5 million in city revenue. Because of its cultural and historical significance, Central Park has been a National Historic Landmark since 1962, and a New York City designated scenic landmark since 1974. It was placed on UNESCO's list of tentative World Heritage Sites in 2017. Real estate and economy The value of the surrounding land started rising significantly in the mid-1860s during the park's construction. The completion of Central Park immediately increased the surrounding area's real estate prices, in some cases by up to 700 percent between 1858 and 1870. It also resulted in the creation of the zoning plan in Upper Manhattan. Upscale districts grew on both sides of Central Park following its completion. On the Upper East Side, a portion of Fifth Avenue abutting lower Central Park became known as "Millionaires' Row" by the 1890s, due to the concentration of wealthy families in the area. The Upper West Side took longer to develop, but row houses and luxury apartment buildings came to predominate the neighborhood, and some were later included in the Central Park West Historic District. Though most of the city's rich formerly lived in mansions, they moved into apartments close to Central Park during the late 19th and early 20th centuries. During the late 20th century, until Central Park's restoration in the 1990s, proximity to the park did not have a significant positive effect on
