Chiesa di San Giovanni Battista

The medieval church of San Giovanni Battista in Bagno Vignoni preserves a plain single-nave interior and two works associated with the village's thermal landscape: an eighteenth-century Sienese painting of Saint Catherine and a detached fresco of the Risen Christ from the portico above the basin.

Why it matters

The church's simple architecture contrasts with the thermal water that defines the central piazza. It preserves the religious history of a settlement that developed around the baths and became a parish centre. The building also holds devotional works once associated with the wider square, linking the church's interior with the artistic history of the thermal basin.

What to notice

The church has a simple facade and a single nave. An eighteenth-century Sienese painting depicts Saint Catherine with Bagno Vignoni in the background, giving the village a place within the saint's iconography. An early-seventeenth-century fresco of the Risen Christ, removed from the chapel on the Loggiato di Santa Caterina above the basin, is preserved inside the church. The paintings connect local devotion with the thermal setting.

Context and history

The parish church developed alongside the medieval settlement around the baths. Saint Catherine of Siena's stays in Bagno Vignoni between 1362 and 1367 belong to the history of the village's religious life and are reflected in the later painting that depicts her with the settlement. When the fresco of the Risen Christ was removed from the loggia chapel for preservation, it became part of the church's collection. The church and detached fresco together document the devotional history of the square and its thermal architecture.
