Big Ben is the familiar nickname for the Great Bell of the clock tower at the Palace of Westminster in London, and its chimes have become shorthand for the city itself in film, television, and online video. Foghorns, by contrast, are maritime warning signals used in low visibility, and their deep tone is widely recognised from harbours and ships. This clip pairs the two sounds, a combination creators often search for when they need both a location cue and an atmospheric mood, which is why it continues to appear in travel edits, documentaries, and dramatic transitions.
