Walk underneath the low, curved concrete roof of this footbridge and, before you cross, tip your head back. Faces and bodies are looking down at you from the vault, life-sized figures made of thousands of tiny mosaic tiles.
This is one of the two Puentes Cáscara, the shell bridges, twin footbridges near the Matadero whose thin concrete vaults arch over the walkway like the inside of an eggshell. Their ceilings were decorated by the Madrid artist Daniel Canogar, who is known for working with projected light and images. For these bridges he turned photographs of ordinary people into mosaic.
The figures float, stretch and drift across the curved ceiling as if they were swimming in the river above your head, or lying on their backs in the grass on a summer afternoon. They are not saints, not kings, not footballers... they are people from Madrid, captured in poses of rest and play. In a city full of statues of the powerful, it is a rare public monument to everybody else.
Stand in the middle and listen too. The curved shell bounces sound back, so voices, footsteps and the bells of bicycles echo strangely under the vault. Children love to shout here, and adults love to pretend they did not. Cyclists slow down without being asked, as if the low roof itself were telling them to.
The bridges are also a quiet lesson in engineering. A thin curved shell of concrete is strong because of its shape, not its thickness, the same principle as an egg, and Spanish engineers of the twentieth century were famous for exactly this kind of daring, elegant concrete. Here the idea serves a simple purpose: shelter for a moment of crossing, a little dark room between two bright banks. Just beside the bridge, on the eastern bank, look for a long glass-and-iron hall. That is where we go next.
