The Call Jueu (Jewish Quarter) is one of Girona's most emblematic areas and one of Europe's best-conserved Jewish neighbourhoods.
One of Girona's most iconic areas is the Call Jueu, or Jewish Quarter, made up of a maze of small streets and courtyards that maintain their medieval aura. It's one of Europe's best-preserved Jewish neighbourhoods and a clear sign of the significance that Jewish culture once had in the city. The Call began to be developed in the 12th century, on C/ de la Força, when Jewish families moved there from existing homes around the Cathedral. The neighbourhood at the time was located in the centre of various districts in what is today known as the Barri Vell, or Old Town. At its peak an average of around 800 people were living in the Call, including doctor, poet, philosopher and rabbi, Mosse ben Nahman, better known in Catalan as Bonastruc ça Porta.
