The Metropolitan City of Florence is bordered by the
Metropolitan City of Bologna in the north, the
province of Ravenna and
Forlì-Cesena in the north-east, the
province of Prato,
Pistoia and
Lucca in the north-west, the
province of Pisa in the west, the
province of Siena in the south and the
province of Arezzo in the east and southeast. Much of its territory lies in the plain of the
Arno river and has thus become an exurban sprawl around the city of Florence. The northeastern part of the metropolitan city, in the
Apennines, remains less developed. Romagna Granducale is the name given to the region lying on the northern slopes of Apennines. Corn, wine and silk are the chief products in the valley regions. Silk manufacturing was an important industry in the medieval times. Renaissance
polymath Leonardo da Vinci was born in the village of
Anchiano, which is a part of the Metropolitan City of Florence. The capital Florence is a well known cultural and a large tourist centre. == Main sights ==
