Caldana: Churches and Marble History

Caldana stretches across the last of the Metalliferous Hills before the Maremma plain. This setting gives the town a distinctive geographical framework: hills and plain meet here in the landscape. At the same time, churches, historic buildings, and stone tell the story of Caldana’s past. Visitors looking for a stay that combines local history with distinctive landscapes will find concrete themes here to guide their exploration.

Hill Country and Stone from Caldana

Northwest of Caldana are the Cave “Marmo Rosso” di Caldana quarries, which remain clearly visible. Stone extraction there continued until 1975. This places two distinct periods side by side: the quarries are visible landscape features today, while their extraction belongs to the town’s history. When taking in Caldana, visitors can also look for traces of the work done with stone.

The history of local materials also includes the pink ornamental stone that was called Portasanta and quarried in Caldana from at least the 16th century. Marble from Caldana was used in numerous architectural monuments in the province of Grosseto and in Pisa, Siena, Florence, Rome, and Berlin. These places show how far the material’s use extended beyond Caldana in architectural history. The local name Portasanta is itself part of the stone’s history; the use of Caldana marble in the cities listed is a separate matter.

For visitors, the contrast between the visible landscape and the knowledge passed down about the material offers a useful way in. The quarries locate the stone concretely northwest of the town; the history of Portasanta and the use of Caldana marble open up a view of architecture in many other places. This makes it possible to explore Caldana’s history in stone both on site and in the wider context of Tuscany.

Churches and Historic Buildings

At the end of the borgo stands the small Oratorio di Sant’Antonio, a church dedicated to Saint Anthony of Padua. The Casa Canonica dates from the 13th century. It was formerly the Pieve di San Biagio, the town’s old church, before the Tempio di San Biagio was built at the end of the 16th century. This sequence of dates gives the town’s history a clear reference point: the Casa Canonica and the later Tempio di San Biagio belong to different periods in Caldana’s religious architecture.

The Palazzo signorile Austini also harks back to another period. The building dates from the 16th century and was the old palace of the Austini, the lords of the castle. Together with the Casa Canonica, it tells of different chapters of the past: here, the town’s former church; there, the palace of a ruling family. This distinction helps visitors read the historic buildings as more than a single layer of history.

The Church of San Biagio in Caldana can also be described by its façade: Ionic pilasters stand in the upper section and Doric ones in the lower section, with a rose window in the center. Inside, a baptismal font made of Portasanta marble is part of the furnishings. Here, the local history of the material meets a specific detail of the church. The church’s treasures are displayed in glass cases.

Only a small part of the former structure of the convent remains. The surviving elements include the entrance door and the corridor of the upper cells. These are individual architectural traces, not a description of a fully preserved complex. This contrast—a largely lost former building and two identifiable surviving elements—offers a different view of the historic heritage from the finely detailed façade of San Biagio.

Choose Caldana as a Travel Destination

If you are considering a stay in Caldana, you can shape it around these themes: the sequence of historic churches and buildings, the architecture of San Biagio, or the history of local stone. In the landscape, the visible quarries northwest of the town add a concrete connection to the surrounding area to this history. Together, they offer a clear reason to get to know Caldana through its buildings and materials—without merging the different stories into one.
