A medieval Manhattan. San Gimignano, Siena, Italy

These medieval towers stand tall over San Gimignano, a small town near Siena in north-central Italy. In the Middle Ages, a town grew up around a church dedicated to Saint Geminianus—San Gimignano in Italian. As well as being a popular stop for pilgrims on their way to Rome, the town prospered thanks to its trade in local Vernaccia wine and saffron, which is grown in the nearby hills. However, when the Black Death struck in 1348, half the population was lost, slowing the town's development and preserving its medieval character to this day.

San Gimignano's most recognisable feature is its skyline, made up of 14 towers. These impressive structures were the result of a rivalry between two families, each competing to build the tallest tower house. By the end of the medieval period, there were 72 towers in the town, although because of wars, other catastrophes and building projects, many were lost. Today, the tallest tower still standing is the Torre Grossa—'big tower' in Italian. Built in 1310, it stands at an incredible 54 metres. It's no wonder that the town is sometimes called the Manhattan of the Middle Ages.
