"Fyris\u00E5n (in English, 'the Fyris river') is a river in the Swedish province of Uppland, which passes through the city of Uppsala and ends in Lake M\u00E4laren.It was formerly called the Full or the Sala river \u2013 Sala referred to the halls (Up-Salir) of the Swedish kings at Gamla Uppsala \u2013 but its name was changed in the 17th century in memory of the Fyrisvellir, marshy plains which had long since been turned to agriculture, but were famous from Norse mythology and as the site of the Battle of F\u00FDrisvellir in the late 10th century.Boats can sail up the river from Lake M\u00E4laren all the way to central Uppsala where two weirs make further progress impossible.
