Paolo Soleri: The Taliesin Apprentice Who Cast Buildings in Dirt, Sold Bells to Pay for Them and Finally Got His Bridge

An architect from Turin who came to the desert in 1947 as a Frank Lloyd Wright apprentice, Paolo Soleri founded Cosanti with his wife Colly in 1956 and spent the rest of his life building by pouring concrete over mounds of earth. His windbells paid for everything, including Arcosanti, and in 2010, at 91, he watched Scottsdale dedicate the only bridge he ever built.

The 30-second version

  • Born in Turin in 1919 and holding a doctorate in architecture, Soleri arrived in 1947 as an apprentice in Frank Lloyd Wright's Taliesin Fellowship and stayed about a year and a half.
  • In 1956 he and his wife Colly founded Cosanti on a few acres of Paradise Valley desert, where he developed earth-casting: concrete poured over shaped mounds of soil, then dug out from underneath.
  • Bronze and ceramic windbells cast at Cosanti funded his buildings and, from 1970, Arcosanti, his experimental 'arcology' town about seventy miles north.
  • The Soleri Bridge and Plaza over the Arizona Canal was dedicated on December 11, 2010, with the 91-year-old Soleri present; its 64-foot pylons, set six inches apart, work as a solar calendar.
  • He died in April 2013 at 93, and the Cosanti Foundation still runs the studio and foundry.

Why he matters

Frank Lloyd Wright made Scottsdale a name in architecture. Paolo Soleri made it an argument. He came to the desert as one of Wright’s apprentices, left after a year and a half, and spent the next sixty years building his own answer a few miles away: half-buried shells of concrete cast over piles of dirt, turned south so the winter sun comes in and the summer sun stays out.

He paid for it with bells. The bronze and ceramic windbells cast at Cosanti funded the buildings, the apprentices and eventually Arcosanti, the experimental town he founded seventy miles north in 1970. They are still poured by hand, and they are still the most honest souvenir the Scottsdale area sells.

Where to find his mark today

Cosanti. His home, studio and foundry on Doubletree Ranch Road, just over the Paradise Valley line, now an Arizona Historic Site. Free to walk, with bronze pours on weekday mornings.

Soleri Bridge and Plaza. The pedestrian bridge over the Arizona Canal at the Scottsdale Waterfront, dedicated on December 11, 2010. The two 64-foot pylons are a solar calendar, and it is the only one of his bridges ever built.

The bells. A bronze bell assembly he made in 1969 hangs at the bridge plaza, and new bells hang in the Cosanti gallery.

Seeing it for yourself

Do Cosanti first and the bridge second. At Cosanti, walk down the steps into the shaded apses, where the air is ten degrees cooler with no machinery involved, and time your visit for a weekday morning pour. Then head to the Scottsdale Waterfront and walk onto the bridge at solar noon. In December the shaft of light between the pylons falls long across the red stripe in the deck; in June it disappears.

If you have time for a third stop, go to Taliesin West, where he started. Seeing the master’s desert camp and the apprentice’s earth-cast answer on the same day is the best architecture lesson in the Valley. In November the bridge plaza is the stage for Canal Convergence.

The full story

Paolo Soleri was born in Turin in 1919 and earned a doctorate in architecture before he came to Arizona. In 1947 he arrived at Frank Lloyd Wright’s Taliesin Fellowship as an apprentice and stayed about a year and a half, long enough to absorb the desert and to start arguing with what he was taught. He also started designing bridges, a habit he kept for the rest of his life without, for decades, getting one built. For the teacher’s side of the story, see Frank Lloyd Wright.

In 1956 he and his wife Colly settled on a few acres of Paradise Valley desert and named the place Cosanti. There he tested earth-casting at full scale: shape a mound of soil and silt into the form of the room you want, pour concrete over it, wait, then dig the dirt out from underneath. Windbells, first ceramic and then bronze, cast on site and sold to visitors, paid for everything. In 1970 the bell money helped him found Arcosanti near Cordes Junction, a prototype for what he called arcology, dense vertical cities that leave the surrounding desert alone.

Scottsdale came calling late. By the Cosanti account, the city’s public art program first approached him about a bridge in 1990; the commission came together in the mid-2000s, when the Waterfront rose along the Arizona Canal and Scottsdale Public Art asked the 86-year-old architect to span it. The ten earth-cast concrete panels in the plaza, about 3,500 pounds each, were made at Cosanti. The Soleri Bridge and Plaza was dedicated on December 11, 2010, ten days before the solstice, so the crowd could watch the pylons’ light do what he said it would. He was 91.

Soleri died in April 2013 at 93. The Cosanti Foundation kept the compound and the foundry running, and in 2020 the architecture school Wright had founded moved its students to Cosanti and Arcosanti after leaving Taliesin West, the master’s school taking shelter at the apprentice’s campus. His Scottsdale years span the boomtown era through the 2010s.

Questions people actually ask

Who was Paolo Soleri?

An Italian architect from Turin who came to Arizona in 1947 to apprentice with Frank Lloyd Wright, then founded Cosanti in Paradise Valley in 1956 and Arcosanti in 1970. He built by earth-casting, funded his work by selling bronze and ceramic windbells, and died in 2013 at 93.

What is the difference between Cosanti and Arcosanti?

Cosanti is Soleri's home, studio and foundry on Doubletree Ranch Road in Paradise Valley, about twenty minutes from Old Town. Arcosanti is the experimental town he began in 1970 near Cordes Junction, about seventy miles north.

Did Paolo Soleri build other bridges?

No. He designed and published bridges for about six decades, and the Soleri Bridge over the Arizona Canal in Scottsdale, dedicated on December 11, 2010, is the only one ever built.

Can you visit Cosanti for free?

Yes. Self-guided visits and the roughly hour-long guided tours are free, with donations encouraged. The bronze pours and tours happen on weekday mornings.
