third of the 18th century, the ever increasing influence of the Parisian model meant that red brick was no longer popular: the city facades were then whitewashed to imitate stone. This is why nowadays, even though the white paint has generally been removed, there are walls with deep grooves carved in brick to imitate ashlar architecture. 19th and 20th century architecture Toulouse's 19th century architecture can be divided into three periods, which sometimes overlapped. In the first half of the century, at the instigation of architect Jacques-Pascal Virebent, the main planned squares were created: the Place du Capitole and the Place Wilson (called place Villeneuve when it was built), whose uniform architecture was inspired by Rue de Rivoli in Paris. From 1830 onwards, Auguste Virebent and his brothers (sons of Jacques-Pascal) developed a factory of low-cost moulded decorations which met with great success and adorned Toulouse facades with numerous terracotta ornaments, far from the austere architecture of their father. Then, in the last third of the 19th century, large Haussmann-style avenues were opened in the town centre, such as the central Alsace-Lorraine street, built in yellow brick to imitate Parisian stone. Banks of the Garonne, Canal du Midi, parks The banks of the Garonne river offer an interesting urban panorama of the city. Red brick dykes from the 18th century enclose the river which was subject to destructive floods. The Pont-Neuf took almost a century to build as the project was so ambitious (1545-1632). It was a very modern bridge for its time, removing the housing on the deck and using techniques such as basket-handle (surbased) arches, openings in the piers and stacked spouts to spread the water, making it the only bridge in Toulouse to withstand the violent floods of the past. Further downstream, the Bazacle is a ford across the Garonne river, in the 12th century the Bazacle Milling Company was the first recorded European joint-stock company. On the left bank of the river, historically a flood-prone bank, stand two former hospitals whose origins date back to the 12th century: the Hôtel-Dieu Saint-Jacques and the Hôpital de La Grave. Isolated on the left bank, victims of the plague and other sick people were thus kept away from the city by the width of the river. Built at the end of the 17th century, the Canal du Midi bypasses the city centre and has linked Toulouse to the Mediterranean
