— — the dish that listened to the sky for fifty-seven years.
“A 305-metre radio dish set into a natural limestone sinkhole, surrounded by green karst hills an hour west of San Juan. For almost six decades it was the largest single-aperture telescope in the world. It mapped the surface of Venus, found the first planets outside our solar system, and sent the 1974 message toward M13. The instrument platform collapsed in December 2020 and the dish is no longer in service, but the bowl is still there in the hills, holding the shape of the listening. from the studio
Each tile is finished by hand in our Knoxville studio. Artwork is slowly infused into the ceramic surface under high heat and pressure, and rests beneath a thin glossy finish. The colour lives in the surface, not on top of it.

The Arecibo Observatory sits in a natural karst sinkhole in the limestone hills of Esperanza barrio, about 16 km south of the coastal city of Arecibo in northern Puerto Rico. The 305-metre fixed spherical reflector was built into the doline so the dish itself could not be steered; aiming was done by moving a 900-tonne instrument platform suspended on cables 150 metres above the bowl. Construction finished in 1963 under Cornell University and the U.S. Department of Defense. The site is part of the U.S. National Register of Historic Places and remains operated by the University of Central Florida for education and atmospheric research.
Three dates carry the place. In 1974 the Arecibo Message — 1,679 binary digits drafted by Frank Drake and Carl Sagan — was beamed toward the globular cluster M13, the first deliberate interstellar transmission of its kind. In 1992 Aleksander Wolszczan and Dale Frail used the dish to confirm the first planets ever detected outside our solar system, in orbit around the pulsar PSR B1257+12. On 1 December 2020, after two support cables failed, the 900-tonne instrument platform fell into the dish, ending the telescope's working life.
The observatory grounds and the Ángel Ramos Foundation Science and Visitor Center reopened to the public in 2023 under the University of Central Florida, with an outdoor viewing platform that looks across the empty bowl. The road in climbs PR-625 from the town of Arecibo through dense karst country; the drive from San Juan is about an hour and a half. The dish itself is no longer collecting data, but the site now functions as an education centre focused on radio astronomy and atmospheric science.
