San Gimignano: Centro Storico

San Gimignano’s medieval skyline survives almost by accident: fourteen tower-houses, out of dozens once built as a display of family power, stand today largely because the Black Death of 1348 emptied the town and froze its urban fabric before it could be modernised like Florence or Siena.

At a glance

San Gimignano is a walled hill town in the province of Siena known for the surviving tower-houses built by its rival noble families between the 12th and 14th centuries. It sits on the old pilgrim road to Rome, the Via Francigena, and its historic centre was inscribed on the UNESCO World Heritage List in 1990.

The town is also associated with two agricultural products that carry protected status today, the white wine Vernaccia di San Gimignano and the local saffron, and with a fresco cycle by Domenico Ghirlandaio in the parish church on the Piazza del Duomo.

Key facts

  • Towers: fourteen medieval tower-houses survive of a much larger original number built by competing noble families.
  • Piazza della Cisterna: centred on an octagonal brick wellhead built in 1237, once the main water point for the town and for pilgrims.
  • Vernaccia di San Gimignano: the first Italian wine to receive DOC status, in 1966, and later upgraded to DOCG.
  • Collegiata frescoes: the Chapel of St Fina inside the Collegiata was frescoed by Domenico Ghirlandaio in 1475.
  • UNESCO status: the historic centre of San Gimignano was inscribed on the World Heritage List in 1990, reference 550.

History

San Gimignano’s early prosperity came from its position on the Via Francigena, the pilgrim and trade route linking Canterbury to Rome, which entered the town through the Porta San Matteo and left through the Porta San Giovanni. Pilgrim traffic and the hostelries along the Via delle Fonti formed the economic base of the town between the 11th and 13th centuries.

The town also traded in saffron, grown locally after the corm was introduced from the eastern Mediterranean in the 14th century. Records held in the Archivio di Stato di Prato, part of the archive of the merchant Francesco di Marco Datini, show San Gimignano saffron being shipped to Bruges over several decades in the late 14th and early 15th centuries.

The Black Death of 1348 killed a large share of the town’s population and halted its growth. Struggling with reduced trade and taxation, San Gimignano surrendered its independence to Florence in 1353, ending its life as a self-governing commune. It is said, though not verified, that the young Florentine notary Giovanni Boccaccio, present among the Florentine delegation, composed part of the Decameron while in the town. The historic centre was inscribed on the UNESCO World Heritage List in 1990.

What you see

The Piazza della Cisterna is the visual heart of the town, its brick paving sloping toward the 13th-century octagonal wellhead at its centre. Around it rise several of the surviving towers, including the twin towers built by the Ardinghelli and Salvucci families, whose rivalry is said to explain their facing positions across the square.

An arch leads north into the Piazza del Duomo, flanked by the Collegiata on one side and the 1239 Palazzo del Podestà on the other. Inside the Collegiata, the nave walls carry a fresco cycle of Old Testament scenes attributed to Bartolo di Fredi, while the Chapel of St Fina in the right transept holds Ghirlandaio’s 1475 frescoes narrating the death and funeral of the young local saint, one scene set against a painted view of the real Piazza della Cisterna.

Practical information

  • Visiting the towers and museums: access and any combined tickets for the civic tower, museums and the Collegiata are best checked on the town’s official tourism channels before travelling.
  • Wine tasting: Vernaccia di San Gimignano can be tasted at producers and wine bars in the town; opening arrangements vary by season.
  • Walking the centre: the historic centre is compact and largely pedestrian, with the two main piazzas a short walk apart.

Getting there

San Gimignano lies within reach of Siena and Florence in Tuscany and remains linked, in spirit if not in modern form, to the old Via Francigena route that once brought pilgrims through the town via Lucca, Pisa, Fucecchio and Poggibonsi. Current road and public transport connections are best checked with local transport operators before setting out.

Nearby

  • Poggibonsi — a town on the old Via Francigena route that once led pilgrims toward San Gimignano.
  • Fucecchio — another stage on the historic pilgrim road linking Lucca to Siena via San Gimignano.
  • Siena — the provincial capital, the historic destination of the same pilgrim route heading south.
