John Lennon, who was murdered outside the nearby Dakota apartment building. The city dedicated Strawberry Fields in Lennon's honor in April 1981, and the memorial was completely rebuilt and rededicated on what would have been Lennon's 45th birthday, October 9, 1985. Countries from all around the world contributed trees, and Italy donated the "Imagine" mosaic in the center of the memorial. It has since become the site of impromptu memorial gatherings for other notables. For 16 days in 2005, Central Park was the setting for Christo and Jeanne-Claude's installation The Gates, an exhibition that had been planned since 1979. Although the project was the subject of mixed reactions, it was a major attraction for the park while it was open, drawing over a million people. Restaurants Central Park contains two indoor restaurants. Tavern on the Green, at Central Park West and West 67th Street, was built in 1870 as a sheepfold and was converted into a restaurant in 1934. The Tavern on the Green was renovated and expanded in 1974; it was closed in 2009 and reopened five years later after a renovation. The Loeb Boathouse restaurant is at the Loeb Boathouse, on the Lake, near Fifth Avenue between 74th and 75th streets. Though the boathouse was constructed in 1954, its restaurant opened in 1983.

One of the main attractions in the park's early years was the introduction of the "Carriage Parade", a daily display of horse-drawn carriages that traversed the park. The introduction of the automobile caused the carriage industry to die out by World War I, though the carriage-horse tradition was revived in 1935. The carriages have become a symbolic institution of the city; for instance, in a much-publicized event after the September 11 attacks, Mayor Rudy Giuliani went to the stables to ask the drivers to go back to work to help return a sense of normality. Some activists, celebrities, and politicians have questioned the ethics of the carriage-horse industry and called for its end. The history of accidents involving spooked horses came under scrutiny in the 2000s and 2010s after reports of horses collapsing and even dying. Supporters of the trade say it needs to be reformed rather than shut down. Some replacements have been
