Prato is a city in Tuscany, Italy, the capital of the Province of Prato. Historically, Prato's economy has been based upon the textile industry. The renowned Datini archives are a significant archive of early medieval documents produced years between 1363 and 1410. The Textile Museum also reflects this history. Prato is also a centre of the slow food movement, with many other local specialities, including cantucci, a type of biscotti, sold by local speciality bakers. Since the late 1950s, the city has been a target of a great immigration, first from southern Italy, then other nationalities. Since the late 1980s a large Chinese community has settled in the city. With more than 180,000 inhabitants, Prato is Tuscany's second largest city and the third largest in Central Italy, after Rome and Florence.
