Within the encircling walls of the town space was at a premium, and the wealthy inhabitants brought in architects to build their houses in the great architectural styles of Siena-Gothic, Pisan Romanesque and Florentine Early Renaissance. In a constant effort to impress their neighbours, the inhabitants built tall towers and at one time there were 72 towers in the small town. Today 14 remain. The decline of San Gimignano began in 1348 when 75% of the population died of the Black Death.
At first sight the town is quite astonishing, the stark towers rising in complete contrast to the terracotta-tiled, ochre-tinted walls of the old buildings. The tallest tower is 200 feet high. The effect is not unlike that of a modern city where the centre thrusts upwards in a group of brash skyscrapers. But there is nothing brash about lovely San Gimignano, where, since the nineteenth century, visitors have flocked to admire the architecture and see the great works of art it possesses.
