Poços de Caldas: Introduction

Ninety million years ago, a caldera roughly thirty kilometers across collapsed here, and the geology has been rewriting itself ever since. The same volcanic activity that produced the sulphurous hot springs also seeded the soil with thorium, zirconium, uranium, and bauxite. A city grew up inside the ring wall. Bathers soak in the mineral waters at Thermas Antonio Carlos. A few kilometers away, Alcoa operates one of the world's largest bauxite mines, and Brazil's first uranium-concentration plant turned the same rocks into fuel for a nuclear reactor at Angra dos Reis. Everything in Pocos de Caldas sits on top of what the volcano left behind.

An aerial tram climbs Morro do Cristo Redentor, ending at a statue of Christ the Redeemer at 1,686 meters - not the famous one in Rio, but a smaller cousin gazing over a different landscape. From the summit you can see the ring of caldera peaks stretching to every horizon, the to...

Poços de Caldas: Glass from Murano, by Way of Minas

Photo credit Thiago Vicente, CC BY-SA 2.5. The glass industry here has an unlikely pedigree. The founders of the factories - Ca'D'oro, Sao Marcos, Veneza, Bonora - were descendants of glassmakers from the Venetian island of Murano, carrying techniques refined over centuries in Italy's lagoon. They brought the knowledge ac...

Poços de Caldas: The Rocks Beneath

A rare zirconium ore was named caldasite for the region. The soils yield thorium, used in some nuclear applications, and enough uranium that Brazil built its first ore-concentration plant here - fuel...

Poços de Caldas: Sister Cities, Scattered

Photo credit José Raphael Santos Netto, Public domain. Pocos de Caldas's sister-city list reads like a thoughtful atlas entry rather than a random assortment. Takasaki, Japan, paired in 1968, for the cherry-blossom resonance with the Japanese tea garden in town. Caldas da Rainha in Portugal, paired in 2001, the thermal-springs town t...
