Los Viajes del Agua is an ancient underground watering system built under Madrid in the 9th century, during its andalusian period, which was essential to the city’s development. The technology, called qanat or karez, was invented in modern Iran 3,000 years ago and uses gravity to transport drinking water from aquifers to the surface without the need for pumping.
Although their original function has been replaced by modern infrastructure, some parts of these canals still exist under Madrid and, incredibly, a continuous flow of water still persists in some of these surviving stretches.
The work features a sound collage with original field recordings from the watering sources in the mountains, the city’s underground canals, the traditional music and festivities of San Isidro (an amazigh shepherd linked to water miracles), and the last places where this water flows on the surface.
The recordings were made in March, May and June of 2025. Produced with DIY microphones (clippy, contact and hydrophones) built in February.
