Sevilla's most well-known symbol is the Giralda. It is a former Muslim minaret that was later adapted to Christian culture by making it a bell tower as part of the Cathedral. What people do not usually know is that many towers around the world have been inspired by the Giralda's architecture. Especially in the US: the second Madison Square Garden in New York City, the clock tower of the Ferry Building in San Francisco, and the Terminal Tower in Cleveland are all examples.
A replica of the Giralda exists in the Country Club Plaza in Kansas City (Missouri)! A real estate developer traveled to Europe in 1922 and visited Sevilla. He was charmed by the tower, and decided to build one in Country Club Plaza. This is the origin of why Sevilla and Kansas City have been twin cities since 1969.
