Basilica di Santa Maria del Tiglio

On the ground where Gravedona meets the lake, Santa Maria del Tiglio raises a banded facade of white Musso marble against dark stone, with a bell tower planted over the entrance — a notable example of Comasco Romanesque architecture. Built as the medieval baptistery, it keeps a Roman altar, early Christian mosaics and a twelfth-century carved crucifix.

Why it matters

Santa Maria del Tiglio is the standout work of Comasco Romanesque on the upper western shore, protected as a national monument. Its value begins below the floor: excavations during the 1953 restoration uncovered an early Christian baptistery of the fifth and sixth centuries, dedicated to Saint John the Baptist, which had served the wide parish territory of the medieval pieve of Gravedona. The tradition even records a sacred area here in Roman times; an ancient altar is walled into the building.

The story here is old and unusually well documented. In the year 823, chroniclers recorded that a fresco of the Adoration of the Magi in the old baptistery seemed to shine by its own light for two days and nights — an event noted in the Annals of Fulda, the great Frankish record of the Carolingian age.

What to notice

The masonry alternates courses of white marble from the Musso quarry with black-grey stone from Olcio, a two-tone dressing that gives the building its singular banded face. Along the eaves runs a frieze of small hanging arches over a sawtooth cornice, and carved fragments from the earlier buildings are set into the walls: the façade includes a sculpted head, possibly from a Roman funerary stele, and round reliefs known popularly as the "breasts of Queen Theodolinda". A bas-relief centaur, a pierced deer and a serpent complete a facade program of temptation symbols.

The tower is square in its lower register and octagonal above the belfry; it stands in line with the portal, following a scheme associated with Rhenish and Burgundian models.

Inside, the hall is nearly square, ringed by two side apses and three eastern apses cut directly into the wall's thickness, with a continuous loggia above triple-arched arcades. Against the north wall hangs the church's great treasure: a wooden crucifix carved in the first half of the twelfth century from poplar and alder, attributed to a Rhenish workshop and counted among the oldest such works in the Diocese of Como; it was restored in 2000. On the counter-facade, a mid-fourteenth-century Last Judgment attributed to Pietro Paolo da Menaggio pairs the blessed and the damned with painted inscriptions of the works of mercy. Fragments of devotional frescoes — Saint Anne, Saint Julian the Hospitaller, an Adoration of the Magi from the late 1400s, a Saint Christopher — survive from the walls' once complete decoration, and a fragment of fifth-century floor mosaic survives in a corner beside traces of the old baptismal basin.

Context and history

The present building went up over the first decades of the twelfth century as the baptistery of the pieve, replacing the paleochristian font; the first document naming it dates to 1154. Its unusual name is explained by a local story of a linden tree — a tiglio — said to have sprouted on the tower, and popular memory attaches the name of Queen Theodolinda to the place, a legend with no documentary basis but a long life.

The tower's octagonal belfry was added over the fourteenth-century square base and only finished in the sixteenth century. After the Council of Trent the interior was modernized, and the 1952–53 restorations peeled this back, recovering the mosaic pavement, the font remains and the fresco fragments. The basilica remains a consecrated church in the parish’s care.
