 They ran downhill into two larger open sewers, and then either to the Seine or to the moats of the fortifications built by Charles V. Documents from 1325 record a sewer called the "Sewer of the Bishop" on the Île de la Cité that ran beneath the Hôtel Dieu into the Seine.A more ambitious covered sewer, three hundred meters long, was built in 1370 from the Rue Montmartre to the moat of the city walls.Another covered sewer was built along the Rue Saint-Antoine toward the Bastille; it had to be diverted to the modern Rue de Turenne in 1413 because it passed too close to the residence of King Charles VI at the Hôtel Saint-Pol, and the aroma disturbed the king and his court.
