Prato ( , ) is a city and comune in Tuscany, Italy, the capital of the Province of Prato. The city lies north east of Tuscany, in the Florentine plain, at an elevation of , at the foot of Monte Retaia (the last peak in the Calvana chain). With 195,213 inhabitants , Prato is Tuscany's second largest city (after Florence) and the third largest in Central Italy (after Rome and Florence). Historically, Prato's economy has been based on the textile industry and its district is the largest in Europe. The textile district of Prato is made up of about 7000 fashion companies, amounting to around 2 billion euros of city's export. The renowned Datini archives are a significant collection of late medieval documents concerning economic and trade history, produced between 1363 and 1410.
