To the left is the long arcade along the north side of the piazza, the buildings on this side are known as the Procuratie Vecchie, the old procuracies, formerly the homes and offices of the Procurators of St Mark, high officers of state in the days of the republic of Venice. They were built in the early 16th century. The arcade is lined with shops and restaurants at ground level, with offices above. The restaurants include the famous Caffè Quadri, which was patronized by the Austrians when Venice was ruled by Austria in the 19th century, while the Venetians preferred Florian's on the other side of the piazza.[citation needed]
