Kellatornid on paljudes maailma paikades tavaline vaatepilt, mõned neist on kunstipärased ehitised, mille näide on Elizabeth Tower Londonis (tavaliselt nimetatakse seda „Big Ben“, kuigi see nimi kuulub ainult torni sees olevale kellale).
Clock towers are a common sight in many parts of the world with some being iconic buildings. One example is the Elizabeth Tower in London (usually called "Big Ben", although strictly this name belongs only to the bell inside the tower).
