Arch vs Tornio

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.

Informations

Tornio (Swedish: Torneå; Northern Sami: Duortnus) is a city and municipality in Lapland, Finland. The city forms a cross-border twin city together with Haparanda on the Swedish side. The municipality covers an area of 1,348.83 square kilometres (520.79 sq mi), of which 161.59 km2 (62.39 sq mi) is water. The population density is 18.18 inhabitants per square kilometre (47.1/sq mi), with a total population of 21,573 (31 July 2020).

It borders the Swedish municipality of Haparanda (in Finnish: Haaparanta). In spite of being a border city Tornio is unilingually Finnish with a negligible number of native Swedish speakers, although this does not count vast numbers of bilinguals who speak Swedish as a second language, with an official target of universal working bilingualism for both border municipalities.
