Suisio

Suisio is a municipality in the Italian region of Lombardy, located about 35 kilometres northeast of Milan and about 20 kilometers west of Bergamo. It had a population of 3 794 inhabitants and an area of 4.6 square kilometres .
The name "Suisio" appears for the first time in a document in the 879 C.E but it's not mentioned the original name written in the document. To reproduce the evolution of the toponym, it's necessary to talk about the Corografia Bergomense that collects, in a chronological order, all the documents which cite the different municipalities in the province of Bergamo. Under the name Suisio, it's mentioned: SEVISIO , SEVIXIO , SOVISIO , SOVIXIO . The conclusion was that the most common forms found in the documents after 1260 C.E. are Sovixio and Sovisio. Another form which is very important is in the code 1387 in the Vatican apostolic library , the so-called "Fondo Patella", which marks the borders of the municipalities of Bergamo between the years 1392-1395 and which presents the form: COMMUNIS DE SUIXIO. In the majority of cases the geographical names are connected with the characteristics of the environment surrounded places and this is true also for Suisio which has an assonance with the river Seveso.
