This impressive structure crowning Nob Hill was built on the site of the Crocker Mansion after the 1906 earthquake and fire. One of the main attractions of the cathedral are the stained glass windows. These windows showcase over 1000 figures, with some of them dating back as far as the 1930s. The gilded bas-reliefs that adorn the doors of the main entrance are cast from Ghiberti's original molds for the Gates of Paradise that adorn the Baptistery in Florence. The cathedral also boasts two labyrinths. The outdoor one is made of Terrazzo stone and the indoor one from limestone.
