Passage: The present Gothic cathedral was begun on the foundations of the previous churches on 1 May 1298; James II the Just was King of Aragon at the time, and Bernat Pelegri was Bishop of Barcelona. The church was built from the east end towards the west end, with a simple west facade completed in 1417.  The cloister was completed in 1448, making the total duration of construction 150 years.  In the late nineteenth century, Miguel Girona i Agrafel offered to complete the neo-Gothic facade and central tower as inspired by the original fifteenth-century design prepared by master Carlí and rearranged and drawn by the architect Josep O. Mestres. This work was completed in 1913 by Girona's children.

Question: How long did it take to build the cloister?
