This is the Italian region which extends from the Apennines over to the Adriatic Sea with a coastline of one hundred and eighty kilometres stretching from the Tavallo to the estuary of the Tronto.
One part of the present day Marches corresponds to the ancient Roman region of Picenum. After the year one thousand, using the administrative divisions established during the medieval period, a Picenum province was formed and by the end of the thirteen hundreds, the region had the boundaries which are still valid today: internally to the west and south west bordered by Umbria and Lazio, to the north by Romagna and to the south by Lazio and Abruzzi.
The coastline forms an angle, with the summit of Mount Conero signalling the end of the Apennines. From the point of view of the climate and that of food production, the region may be divided into three longitudinal zones - coastal, hill country and mountain. Agriculture constitutes the main activity and achieves good results. In cultivation are wheat, maize, vines, tobacco, sugar beet and various vegetables. The rearing of stock is also important, especially beef, which, as well as the large quantity produced, can also boast of the high quality which is representative of Marchian breeds. There are also pigs, sheep and farmyard animals which are largely exported to other regions particularly Lazio. The fishing industry is of great importance to the coastal areas through its naval yards (Ancona, San Benedetto del Tronto) and its fishing fleet.
