Santa Maria della Spina: The Gothic Jewel on the Lungarno Pisano

Not far from the tourist bustle of the Leaning Tower, nestled like a precious casket on the banks of the Arno, stands one of the most surprising masterpieces of Italian Gothic art: the sanctuary of Santa Maria della Spina. This small church, slender and richly decorated, seems to have emerged from a medieval fairy tale. Its history is intertwined with one of the most poignant relics of Christ’s Passion and with the genius of the great Pisan master sculptors.

History and Devotion: The Sacred Thorn

The beating heart of this place of worship is a relic of extraordinary evocative power: a Thorn from Christ’s crown. It is a woody, sharp twig, about 8 cm long, belonging to the zizyphus (jujube) species, whose thorns would have formed a sort of “helmet” on the Savior’s head.

The relic arrived in Pisa between 1266 and 1333, perhaps brought by a crusader returning from the Holy Land. Its arrival marked a turning point: in 1333, the Thorn was solemnly transferred to a small pre-existing oratory, dedicated to Santa Maria del Ponte Novo. To worthily house this direct testimony of the Passion, the building was completely transformed and enlarged, taking the name Santa Maria della Spina and becoming a destination for pilgrimage.

The miracles attributed to the intercession of the relic are attested by ancient postils in the oratory’s missals. Today, the Thorn is no longer inside the sanctuary but is kept in a precious gilded and silvered tabernacle in the nearby church of Santa Chiara, within the hospital of the same name. Here, a silent and moving devotion continues to live on: the faithful, especially relatives of patients, leave little notes with prayers and requests for graces behind the glass that protects it.

Architecture: A Masterpiece of Gothic Sculpture

The sanctuary is a triumph of Pisan Gothic, a concentration of spires, statues, tracery, and polychrome marble that seems to defy the laws of gravity. The two-nave building was radically remodeled in the 14th century to accommodate the relic.

The Sculptural Face

The western facade, the one facing the river, is a true story in stone. It is dominated by three slender spires topped with tabernacles. The central one houses a Madonna and Child which, after the 1993 restorations, scholars believe may be attributed to the great Giovanni Pisano. On either side of the two doors, framed by panels of pink marble, two rose windows open.

The Gallery of Apostles

The southern side is characterized by the famous gallery of apostles, likely inserted precisely on the occasion of the Thorn’s arrival. The statues, surmounted by four tabernacles with male figures and putti, are attributed to the workshop of Giovanni Pisano and show a strong influence of Sienese art. This loggia, with its trefoil arches and perforated tympanums, creates a play of light and shadow of extraordinary elegance.

The Artworks

Among the many sculptures adorning the exterior, the following stand out:

• The **Madonna and Child with angels** on the summit of the eastern spires (now a copy), perhaps the work of **Nino Pisano**.

• Another **Madonna and Child** by **Giovanni di Balduccio**, placed under a corner niche.

• Inside, on the high altar (dating from 1521), is the venerated **Madonna della Rosa**, a full-figure marble statue with traces of ancient polychromy, attributed to **Andrea and Nino Pisano**. At her sides, statues of **Saint Peter and Saint John**.

The interior, more sober, is divided into two spaces: the raised choir, which corresponds to the ancient oratory, and the nave resulting from the 14th-century expansion. They are separated by three arches and covered by a beautiful painted wooden truss ceiling by Nicola Torricini.

How to Visit and Useful Information

The sanctuary of Santa Maria della Spina is located on Lungarno Gambacorti, in a panoramic position on the Arno River, a few minutes’ walk from the Piazza dei Miracoli.

For a complete visit, we suggest a small “artistic and devotional pilgrimage”:
1. Admire the architectural jewel: Take time to observe the details of the facade and the gallery of apostles. Look for the differences between the sculptures attributed to the various masters.
2. Cross the threshold: Enter to breathe the intimate atmosphere of the interior and pray before the Madonna della Rosa.
3. The relic’s path: Then proceed to the church of Santa Chiara (at the hospital of the same name, on Via Roma) to venerate the Sacred Thorn in the place where it is now kept and where a living popular devotion continues.

Tip for history enthusiasts: Observe the rear (eastern) part of the church. You will notice that the single-light windows are different from the triple-light windows originally planned. This change was necessary to better support the weight of the tall spires, a detail that reveals the technical challenges faced by the medieval builders.

Curiosities and Traditions

• **A “moved” sanctuary**: Between 1871 and 1875, the entire building was dismantled and raised by about one meter to preserve it from the Arno’s floods. An extraordinary engineering operation for the time!

• **Searching for the coat of arms**: On the side facade, look for the **coat of arms of the Gualandi family**. Its presence recalls that for the 14th-century expansion, their consent was needed for the demolition of a loggia they owned.

• **The devotion that is reborn**: Although public worship in the Spina church waned after the relic’s transfer in 1948, in the church of Santa Chiara a “new season” of intimate and personal faith has opened, witnessed by the many prayer notes left by the faithful.

The sanctuary of Santa Maria della Spina is not just a monument: it is a place where art, history, and faith merge into a unique experience. It represents the Pisan devotion to the Virgin and the Passion of Christ, embodied in an architecture so precious and fragile it seems like marble lace, miraculously surviving time and the waters of the river.
