Spires of Naples Historical Timeline

The three main guglie belong to different crises and patrons. Their order through the city is chronological only in broad outline: the first answers an eruption, the second a plague and a long construction interruption, and the third presents the Immaculate Virgin through eighteenth-century public subscription.

Chronology

1. 1631 A major eruption prompts the votive project that becomes the Spire of San Gennaro; its column still stands in the square dedicated to Cardinal Sisto Riario Sforza.
2. 1636 Work begins on San Gennaro’s spire under Cosimo Fanzago; the completed column turns deliverance into a permanent vertical marker in the historic centre.
3. 1650 San Gennaro’s spire is completed, giving the eruption votive its finished form and statue-topped silhouette.
4. 1656 Work begins on San Domenico after the plague; the project establishes the only one of the three main Neapolitan spires that is strictly a plague column.
5. 1680 Construction of San Domenico is suspended while Francesco Antonio Picchiati documents Roman remains beneath the site; the half-height unfinished shaft records archaeology interrupting a Baroque commission.
6. 1737 Domenico Antonio Vaccaro completes San Domenico under Charles III; the finished guglia now rises in Piazza San Domenico Maggiore above the excavated ancient city.
7. 1747 Work begins on the Spire of the Immaculate Virgin in Piazza del Gesù Nuovo, designed by Giuseppe Genoino and funded through public donations after Jesuit Francesco Pepe refuses royal patronage.
8. 1750 Bottiglieri and Pagano’s sculpture completes the Immaculate spire; its elaborate Baroque surface and Marian image remain legible from the square without an interior visit.

Survival and restoration

The spires survive as exposed street monuments, so their conservation is not the same as preserving a sealed interior. San Domenico’s documented restoration began in 2005 and was supported by public and private bodies. Across all three, the practical act of survival is continued maintenance of stone, stucco and sculpture in busy squares.

The monuments are also arguments about who could speak for the city. San Gennaro makes a cardinal’s square and the city’s patron saint answer a natural disaster; San Domenico turns a Dominican setting and the memory of epidemic into a public shaft; the Immaculate commission uses donations to make Marian protection a shared civic act rather than a private royal gift. Their inscriptions and statues therefore belong to the political as well as devotional history of Naples.

The location of each column keeps that history active. San Gennaro is read with the cathedral quarter, San Domenico with the university and church complex around its piazza, and the Immaculate spire with the Gesù Nuovo frontage and the movement through the historic centre. A visitor does not need to enter a monument to understand the sequence: the surrounding streets supply the scale, procession routes and everyday activity against which each silhouette was designed.

Restoration is necessarily public. Scaffolding, stone cleaning and the protection of sculptural details take place in squares that continue to serve residents and worshippers. The Comune reported that San Gennaro was made safe after a stone fall in 2021 but still requires restoration, while a restoration-design contract for the Immaculate spire was reported as awarded in January 2026. The 2005 San Domenico campaign shows that a guglia is maintained as civic infrastructure, not merely admired as an old object. Comparing the three today means noticing both their finished Baroque language and the practical work that keeps exposed surfaces legible in traffic, weather and changing urban use.

The three columns also make time visible without a museum label. Their sculptural programmes face crowds, processions and ordinary pedestrians, so the monuments continue to work as public memory even when no ceremony is taking place. The different patrons and disasters explain why a walk between the piazzas is more informative than treating one guglia as a representative sample of all three.
