Santa Maria della Spina is a small church in the Italian city of Pisa. The church, erected around 1230 in the Pisan Gothic style, and enlarged after 1325, was originally known as Santa Maria di Pontenovo for the newer bridge that existed nearby, collapsed in the 15th century, and was never rebuilt.
The name of della Spina ("of the thorn") derives from the presence of a thorn, putatively part of the crown of thorns placed on Christ during his Passion and Crucifixion. The relic was brought to this church in 1333. In 1871 the church was dismantled and rebuilt on a higher level due to dangerous infiltration of water from the Arno river. The church was altered in the process, however, and John Ruskin, who visited Pisa in 1872, was outraged about the restoration.
The church of Santa Maria della Spina has always been administered by the city, except for short interruptions in the seventeenth and eighteenth centuries when it fell to the responsibility of the local hospital.
The church is one of the most outstanding Gothic edifices of Europe: it has a rectangular plant, with an external facing wholly composed of marble, laid in polychrome bands. The exterior appearance is marked by cusps, tympani and tabernacles, together with a complicated sculpture decoration with tarsiae, rose-windows and numerous statues from the main Pisane artists of the 14th century. These include Lupo di Francesco, Andrea Pisano with his sons Nino and Tommaso, and Giovanni di Balduccio.
The façade has two gates with lintelled arches. Among these lies the tabernacle with the statues of Madonna with the Child and two Angels, attributed to Giovanni Pisano. Two niches open in the upper part of the façade: these houses the statue of Christ among the two Annunciation ones, and two other angels.
