Chiesa di San Giovanni Battista

Facing Piazza Peretti in the old hill town, San Giovanni Battista layers nine centuries of worship behind a sober classical facade. Restored at the turn of the millennium, it subsequently housed the Museo Sistino, where the Piceno's medieval painters meet the legacy of Pope Sixtus V.

Why it matters

This is the principal church of Grottammare's historic core and one of the few parish buildings in Italy whose documentation reaches back to the fourteenth century: the municipal heritage page records that the first document naming the ecclesia Sancti Iohannis dates to 1391, with the church's origins as a pieve suggesting a founding centuries earlier still. Set into the fabric of the Vecchio Incasato, it holds the corner of Piazza Peretti and gives the square the theatrical framing the municipality describes — three entrances arranged like the triumphal-arch composition of early Christian basilicas, echoing what the sources call the typum Trinitatis.

The neoclassical interior reflects the architectural sobriety associated with Sixtus V and includes a rare full Liberty decorative cycle. The Museo Sistino , the diocesan collection of sacred art installed in the church after its restoration, includes a signed Vittore Crivelli polyptych and a gift from a Renaissance pope alongside the parish's own art.

What to notice

The austere facade with a triangular pediment, lightly projecting lesene and four symmetrical niches, its central window echoing the portal below. The church has a single nave covered by a lowered barrel vault in five bays, Doric entablatures on semi-columns and fluted columns, and Baroque side altars holding reliquary busts of Santa Lucia and of the church's own patron.

In the early twentieth century, the San Benedetto painter Giuseppe Pauri covered the church with an Art Nouveau programme that is unusual in a parish setting: ceiling canvases of Saint John in the desert flanked by the patron saints Patrick and Paterianus, the glorification of the Baptist, and a Lamentation. The high altar is Pietro Maggi's classical edicola with its wooden statue of the Madonna Addolorata; Maggi, the Ticinese architect who rebuilt the church between 1792 and 1809, also worked on the adjacent theatre, so church and Teatro dell'Arancio share a designer.

The organ, installed in 1884 and attributed to Carlo Carletti, reuses an eighteenth-century case and was given by Bishop Vincenzo Franceschini.

Context and history

The church's long life divides into four chapters. First, the medieval pieve: a baptismal mother-church for the coast, documented by name in 1391 and plausibly rooted in the ninth or tenth century. Second, the post-Tridentine expansion of 1620 to 1624, which enlarged the building for a growing town whose most famous son, Felice Peretti, had taken the papal name Sixtus V a generation earlier.

Third came the rebuilding that created today's interior. Between 1792 and 1809 Pietro Maggi restored and reorganised the church according to what the municipal page calls the architectural sobriety wanted by Sixtus V and the rigour of the local bishop, Monsignor Bacher — a deliberately unadorned classicism that still defines the space. Fourth, the modern era: Giuseppe Pauri's Liberty fresco cycle in the early twentieth century, and the long restoration that ended with the church's reopening in 2002, after which it also housed the Museo Sistino as part of the Musei Sistini del Piceno network.

The church anchors Piazza Peretti, whose surrounding architecture includes the town's civic clock installations and the theatre.
