San Gimignano

San Gimignano’s downfall came in 1348, when the city was hit by an epidemic of plague (the Black Death).

An excerpt from the article 17 facts about San Gimignano

The epidemic of the Black Death reached all of Europe at the time, and between 30 and 60 percent of the continent’s population died as a result. The plague also decimated the population of San Gimignano and the city succumbed to the rule of Florence.

Several Gothic palaces in the Florentine style were built in the city, and the height of many towers was lowered, leveling them to the height of the houses. It never again returned to its former glory, its development was little over the years and the city remained in its medieval state, becoming one of the best-preserved medieval cities in Europe.
