A series of 24 information panels have been put on the most important bridges and river banks along the Tiber in Rome. The weatherproof panels have information about the history of the older bridges, the hydraulic engineering features of the river, such as dams and weirs and the wild life that lives in the centre of the city. In the area of the Porto di Ripetta, Ripa Grande and Tor di Nona, the water was once harnessed to operate floating grain mills attached to the bridges. The panels also indicate the sites of historic floods, and beaches and islands that have disappeared as the course of the river has altered over the centuries.
The new panels are part of a project called Teveredamare, supported by the environmentalist group Marevivo. The project will be completed next year with another 24 panels.
