While the city of Bruges has its medieval character beautifully preserved, like all cities buildings change use and status. St Saviours has undergone numerous changes and renovations throughout its history. It was not originally built as the cathedral of the city. It wasn't until the 19th century that it became the cities main cathederal.

Before this the building itself was not very cathedral-like. It was much smaller and far less impressive than the other cathderals of Brugge. So a higher and more impressive tower was built to bring St. Salvator's up to its new status as the cities catherderal.
