1967, and was designated a National Historic Civil Engineering Landmark in 1972. In addition, it was placed on UNESCO's list of tentative World Heritage Sites in 2017. A bronze plaque is attached to the Manhattan anchorage, which was constructed on the site of the Samuel Osgood House at 1 Cherry Street in Manhattan. Named after Samuel Osgood, a Massachusetts politician and lawyer, it was built in 1770 and served as the first U.S. presidential mansion. The Osgood House was demolished in 1856. Another plaque on the Manhattan side of the pedestrian promenade, installed by the city in 1975, indicates the bridge's status as a city landmark. Culture The Brooklyn Bridge has had an impact on idiomatic American English. For example, references to "selling the Brooklyn Bridge" abound in American culture, sometimes as examples of rural gullibility but more often in connection with an idea that strains credulity.

Parker and William McCloundy were two early 20th-century con men who may have perpetrated this scam successfully on unwitting tourists, although the author of The Brooklyn Bridge: A Cultural History wrote, "No evidence exists that the bridge has ever been sold to a 'gullible outlander'". As a tourist attraction, the Brooklyn Bridge is a popular site for clusters of love locks, wherein a couple inscribes a date and their initials onto a lock, attach it to the bridge, and throw the key into the water as a sign of their love. The practice is officially illegal in New York City and the NYPD can give violators a $100 fine. NYCDOT workers periodically remove the love locks from the bridge at a cost of $100,000 per year. To highlight the Brooklyn Bridge's cultural status, the city proposed building a Brooklyn Bridge museum near the bridge's Brooklyn end in the 1970s. Though the museum was ultimately not constructed, the plans had been established after numerous original planning documents were found in Williamsburg. These documents were given to the New York City Municipal Archives, where they are normally located, though the documents were briefly displayed at the Whitney Museum of American Art in 1976. Media The bridge is often featured in wide shots of the New York City skyline in television and film and has been depicted in numerous works of art. Fictional works have used the Brooklyn Bridge as a setting; for instance, the dedication of a portion of the bridge, and the
