Basilica di San Giovanni Battista (Oneglia)

Oneglia’s principal church rises over Piazza San Giovanni beneath a Baroque dome. Begun in 1739 and consecrated in 1762, it became a minor basilica in 2017 and preserves marble altars, side chapels and works from several periods.

Why it matters

San Giovanni Battista is the religious and civic anchor of Oneglia, the eastern half of Imperia and a town that traded in oil and sailed its own ships long before it was merged with its rival Porto Maurizio. "Duomo" of Oneglia is the label the parish's own history archive applies to the church, while the national tourism portal places it at the heart of the old town, steps away from what was once a working crossroads of commerce by the port. When the Diocese of Albenga-Imperia announced in June 2017 that Pope Francis's Congregation for Divine Worship had elevated the collegiate church to the rank of minor basilica, it stressed the building's historical importance and artistic beauty as the very qualities the Vatican decree demands. The church remains an active parish, and the feast of its patron saint is part of the town’s annual calendar.

What to notice

In front of the portals, the paving uses the Ligurian rissêu technique, setting white and black sea pebbles into geometric and naturalistic patterns. The consecration plaque of 1762 runs above the main portal.

The interior follows a Latin cross plan with three naves and a dome; the history archive of the University of Genoa measures the building at 57.42 metres long, 22.15 metres wide and 26.50 metres to the top of the dome, proportions that make it one of the physically largest churches of the immediate coast. The eighteenth-century high altar in polychrome marbles and the wooden choir behind it are prominent features. Other works along the aisles include a sixteenth-century marble tabernacle by Pace Gaggini, choir canvases of the Visitation and the Baptism of Christ painted around 1900 by the Parma painter Gainotti and the Turin painter Luigi Morgari respectively, a Madonna attributed to the workshop of Anton Maria Maragliano bought in Genoa in 1718, and in the Chapel of the Holy Trinity a crucifix by the Burgundian sculptor François La Croix, active in western Liguria at the end of the seventeenth century.

Three cannonballs embedded in the apse masonry are associated with the French naval bombardment of October 1792, when revolutionary ships shelled the town.

Context and history

The archive record compiled by the University of Genoa's FOSCA project dates the present church precisely: the foundation stone was blessed on 24 June 1739, the feast of St John the Baptist, by the bishop of Albenga. Construction stalled when the War of the Austrian Succession swept the coast — the national portal notes war damage around 1745 — and the people of Oneglia completed the work with donations and labour. The church was consecrated in 1762, as the inscription on the facade still documents. That facade itself is a later creation: designed only in the nineteenth century and completed between 1832 and 1838 on the model of Santa Maria della Quercia in Rome, it gives the building its neoclassical face above a baroque body, crowned by statues of the Baptist flanked by Saints Peter and Paul.

The earthquake of 1887, which devastated much of the Ligurian coast, forced repeated repairs, and its more recent history includes an ecclesiastical honour: on 20 June 2017 the Congregation for Divine Worship signed the decree that made San Giovanni Battista a minor basilica, binding it specially to the papal see. Bishop Guglielmo Borghetti read the decree publicly during the patronal feast that same month.
