london - The clocks of London's Big Ben hit for the last time on Monday at noon (English). The Elizabeth Tower, which is the 13.7-tonne heavy bell which is officially called Big Ben, will be refurbished in the coming years.
Big Ben is actually the name of the heaviest of the five clocks in the 96-meter-high Elizabeth tower that stands on the River Thames. In general, the whole tower is called so.
Only at major events like old and new, the clock will sound. In other cases, the health of the construction workers can not be guaranteed due to the loud noise.
