Arch vs Lecco

Informations

An arch is a vertical curved structure that spans an elevated space and may or may not support the weight above it, or in case of a horizontal arch like an arch dam, the hydrostatic pressure against it. Arches may be synonymous with vaults, but a vault may be distinguished as a continuous arch forming a roof.

Arches appeared as early as the 2nd millennium BC in Mesopotamian brick architecture, and their systematic use started with the ancient Romans, who were the first to apply the technique to a wide range of structures.

Lecco (US: , Italian: [ˈlekko], locally [ˈlɛkko] (listen); Lecchese: Lècch [ˈlɛk]) is a city of 48,131 inhabitants in Lombardy, northern Italy, 50 kilometres (31 mi) north of Milan.It lies at the end of the south-eastern branch of Lake Como (the branch is named Lake of Lecco / Lago di Lecco). The Bergamo Alps rise to the north and east, cut through by the Valsassina of which Lecco marks the southern end. The lake narrows to form the river Adda, so bridges were built to improve road communications with Como and Milan. There are four bridges crossing the river Adda in Lecco: the Azzone Visconti Bridge (1336–1338), the Kennedy Bridge (1956) and the Alessandro Manzoni Bridge (1985) and a railroad bridge. Lecco was also Alpine Town of the Year 2013.Elevated to province by decree of the President of the Republic of 6th March 1992, Lecco obtained the title of city on 22nd June 1848. Famous for being the place where the writer Alessandro Manzoni set “The Betrothed”, the city is located in one of the vertexes of the Larian Triangle.

It overlooks the eastern branch of Lake Como and is included in the Orobic Prealps, between the Grigne mountain chain and the Resegone. As strategic crossroads for Valtellina, Lecco assumed increasing importance during the Middle Ages when it was annexed to the Duchy of Milan following the Peace of Constance. During the second half of the 19th century, under the Austrian dominion, the city went through a particularly flourishing period during which palaces and arcades in neoclassical style were constructed. After the Unity of Italy, Lecco established itself as one of the most important industrial centers of the nation thanks to the development of the steel industries, already active in the 12th century. For this reason, Lecco is also called “the Iron city”.
