Origin of the name La Sonnaz

The three municipalities put forward the name La Sonnaz to the Municipalities Department on 26 September 2002. On 8 November the nomenclature commission suggested « Lossy » instead. That idea was dropped on 28 January 2003, La Sonnaz was chosen and the federal offices gave a favourable opinion. The river appears in the coat of arms as a silver wave.[1][2]

Founding of La Sonnaz

La Sonnaz unites La Corbaz, Cormagens and Lossy-Formangueires, 833 inhabitants in legal population on 31 December 2001 over 6.90 km². Lossy-Formangueires was itself the product of the 1982 merger. The communal assemblies adopted the agreement on 20 May 2003, the Grand Council passed the decree on 12 September and the merger took effect on 1 January 2004, with state aid of 375'636 francs. The arms show a silver rose on blue, recalling the lords of Thudingen, advocates of the church of Belfaux, the wave of the river, and a gold water wheel on red for the two former mills, at Lossy and at the confluence with the Sarine. The red and gold come from the three former municipalities.[1][2][3]
