versions of the origin of the name of the tower. The first version says

the bell. Another says that the heariest bell at the moment (13.7 tonns)
got its name after Benjamin County, a very famous boxer in the
heavyweight division at the time. Construction. The tower was built on
the design of English architect Augustus Pugin in 1858.
