streetlights, removed nearly all of them in 1957. A gas lamp is located at N. Holliday Street and E. Baltimore Street as a monument to the first gas lamp in America, erected at that location. However, gas lighting of streets has not disappeared completely from some cities, and the few municipalities that retained gas lighting now find that it provides a pleasing nostalgic effect. Gas lighting is also seeing a resurgence in the luxury home market for those in search of historical authenticity. The largest gas lighting network in the world is that of Berlin. With about 37,000 lamps (2014), it holds more than half of all working gas street lamps in the world. In central London around 1500 gas lamps still operate, lighting the Royal Parks, the exterior of Buckingham Palace and almost the entire Covent Garden area. The Park Estate in Nottingham retains much of its original character, including the original gas lighting network. In the United States, more than 2800 gas lights in Boston operate in the historic districts of Beacon Hill, Back Bay, Bay Village, Charlestown, and parts of other neighborhoods. In Cincinnati, Ohio, more than 1100 gas lights operate in areas that have been named historic districts. Gas lights also operate in parts of the famed French Quarter and outside historic homes throughout the city in New Orleans. South Orange, New Jersey, has adopted the gaslight as the symbol of the town, and uses them on nearly all streets. Several other towns in New Jersey also retain gas lighting: Glen Ridge, Palmyra, Riverton, and some parts of Orange, Cape May, and Cherry Hill. The village of Riverside, Illinois, still uses its original gas street lights that are an original feature of the Frederick Law Olmsted planned community. Manhattan Beach, California, has a gas lamp section in which all the sidewalks are lit by public gas lamps. Disneyland has authentic 19th century gas lamps from Baltimore along the "Main Street, U.S.A." section of the theme park. Many gas utility companies will still quote a fixed periodic rate for a customer-maintained gas lamp, and some homeowners still use such devices. However, the high cost of natural gas lighting at least partly explains why a large number of older gas lamps have been converted to electricity. Solar-rechargeable battery-powered gas light controllers can be easily retrofitted into existing gas lamps to keep the lights off during daylight hours and
