The cost of Big Ben was £2401 It should be noted that "Big Ben" is not the tower or the clock but just the bell. The cost of UKP £2,401 is only for casting the bell. There was an adjustment (a credit) of UKP 1,829 from the metal reclaimed from a previous bell. As a result the actual invoice submitted, on 28th May 1858, was for UKP £572.
The bell at the Leaning Tower of Pisa was intended to be used as a church bell for the nearby cathedral, signaling important events such as services, celebrations, and community announcements. Its construction began in the 14th century, but due to the tower's famous tilt and structural issues, the bell was not installed until much later. The bell serves not only a functional purpose but also adds to the architectural significance of the tower.
