Cosanti: Soleri's Bell Foundry and the Name That Means 'Against Things'

Cosanti is a few acres of half-buried concrete domes where Paolo Soleri spent fifty-seven years building by pouring concrete over mounds of dirt. Its name rejects materialism; its income came from selling objects, the windbells still cast there on weekday mornings. Those bells paid for Arcosanti, his city 70 miles north.

In one line

Cosanti: Paolo Soleri's studio, home and bell foundry on Doubletree Ranch Road in Paradise Valley, where bronze and ceramic windbells are still cast. Say 'Cosanti' and a local hears a bell: the word names the place and the chimes hanging on half the patios in the Valley.

Also called Cosanti bells, Soleri bells, Cosanti Originals, Soleri windbells.

The 30-second version

  • Paolo Soleri and his wife Colly began Cosanti on about five acres of Paradise Valley desert in 1956, roughly a decade after he arrived as a Taliesin apprentice.
  • The name joins the Italian cosa, thing, with anti; the Cosanti Foundation reads it as 'against things,' a rejection of hyper-consumerism.
  • Soleri pioneered earth-casting here in 1956: concrete poured over shaped mounds of soil, then the dirt dug out from underneath.
  • Its late-1950s and early-1960s structures earned Cosanti a place on the Arizona register of historic places; the Cosanti Foundation, founded in 1965, runs it.
  • Bronze pours and guided tours run Monday through Friday, with tours at 9:15 a.m.; the gallery opens daily.

Who said it first

Paolo Soleri, from the Italian cosa (thing) and anti, read by his foundation as 'against things'

What it means

Cosanti is two things at once in the Valley. It is a place: the earth-cast studio, home and foundry that Paolo Soleri and his wife Colly began on Doubletree Ranch Road in 1956. And it is an object: the bronze and ceramic windbells cast there, which hang from patio beams and front-door ramadas all over metro Phoenix. “We got them a Cosanti” is a complete housewarming sentence.

The place looks like nothing from the road, a hedge and a gravel lot. Behind it are half-sunken rooms, concrete shells and quarter-sphere apses turned south so the winter sun reaches in and the summer sun does not. Soleri built them by earth-casting: shape a mound of soil, pour concrete over it, let it cure, dig the soil out. You can still see the grain of the dirt in the ceilings.

The Cosanti park guide covers the visit in detail, and the Paolo Soleri profile covers the man. This page is about the name and why locals use it.

Where you’ll meet it

On housewarming lists, in the Cosanti gallery itself, on the architecture guide, in directions to the Paradise Valley side of Doubletree Ranch Road, and inside the word Arcosanti, which Soleri built from it.

Where the word came from

Soleri, born in Turin and trained as an architect, came to Taliesin West in 1947 as an apprentice in Frank Lloyd Wright’s Fellowship. He stayed about a year and a half, parted ways with Wright, spent time back in Italy, and returned to Arizona. In 1956 he and Colly settled on about five acres of desert in what is now the Town of Paradise Valley and named the place themselves.

The name is Italian, and it is a manifesto. Cosa means thing; anti is where the readings split. The Cosanti Foundation, which Paolo and Colly established in 1965, explains it as “against things,” a rejection of hyper-consumerism and an argument for living more fully with less. Other accounts read anti in its older Italian sense of “before,” which gives the softer gloss quoted for decades: there are things more important than objects. Both readings land in the same place.

The irony is the part locals enjoy. Soleri spent the next half century making things, beautiful ones, by the thousand, because the bells paid for the buildings, for the apprentices, and from 1970 for Arcosanti, the town he named by joining Cosanti to his other coinage, arcology.

What it is not

Cosanti is not in Scottsdale, despite how often Scottsdale guides claim it; it sits just west of the city line in Paradise Valley. It is not Arcosanti, the experimental town 70 miles north. And it is not a museum piece: it is still a working foundry with a gallery, run by the foundation.

The fine print

Status. The foundation credits the structures built in the late 1950s and early 1960s with earning Cosanti a place on the Arizona register of historic places. The original building, the Earth House, served later as a student dormitory; studios, a performance space, a pool and the gallery fill out the site.

Visiting. Cosanti’s gallery is open Monday through Saturday from 9 a.m. to 5 p.m. and Sunday from 11 a.m. to 5 p.m. Guided tours run Monday through Friday at 9:15 a.m., and the bronze pours happen on weekdays only. Wandering on your own is welcome.

The bridge. Soleri designed bridges all his life and saw one built: the Soleri Bridge and Plaza over the Arizona Canal at the Waterfront, dedicated on December 11, 2010, when he was 91. It is the best place to see his work without leaving Old Town.

The neighbors. Cosanti is one of two handmade artist compounds in this part of the Valley; the other is the Cattle Track Arts Compound, ten minutes south. Soleri died in April 2013, at 93, and the foundation still runs the studio and pours the bells.

Questions people actually ask

What does Cosanti mean?

It is Paolo Soleri's coinage from the Italian cosa, thing, and anti. The Cosanti Foundation translates it as 'against things,' a stand against materialism; other accounts read anti as 'before' and give the gentler sense, 'there are things more important than objects.'

Is Cosanti in Scottsdale?

No. It is at 6433 East Doubletree Ranch Road in the Town of Paradise Valley, just west of the Scottsdale line. Most visitors reach it from Scottsdale in fifteen or twenty minutes.

When can you see the bronze pour at Cosanti?

Pours, like the guided tours, run Monday through Friday mornings; the tour starts at 9:15 a.m. The gallery is open Monday through Saturday from 9 a.m. to 5 p.m. and Sunday from 11 a.m. to 5 p.m. Check before you go, since schedules change.

What is the difference between Cosanti and Arcosanti?

Cosanti is Soleri's studio and foundry in Paradise Valley, begun in 1956. Arcosanti is the experimental town he began in 1970 about 70 miles north, paid for largely by the bells made at Cosanti.
