The Twenty Francs coin is a denomination of the Swiss Franc. Given that Switzerland has four official languages, the Franc has three different names: Franken in German, franc in French and Romansh, and franco in Italian.
In regular circulation, the denomination is served by a banknote. These coins are non-circulating legal tender made for collectors. They are issued in topical series, celebrating various aspects of Swiss heritage or nature.
The edge is usually inscribed with the motto DOMINUS PROVIDEBIT (The Lord will provide - a quote from the Bible, Genesis 22, 8), and thirteen stars representing the original thirteen cantons of the Swiss Federation.
This coin commemorates the 1,500th anniversary of the Abbey of Saint-Maurice d'Agaune.
The Abbey of Saint Maurice, Agaunum (French: Abbaye de Saint-Maurice d'Agaune or Saint-Maurice-en-Valais) is a Swiss monastery of "canons regular" (priests) in Saint-Maurice, Canton of Valais, which dates from the 6th century. It is situated against a cliff in a section of the road between Geneva and the Simplon Pass (to northern Italy). The abbey itself is a territorial abbacy and not part of any diocese. It is best known for its connection to the martyrdom of the Theban Legion, its original practice of perpetual psalmody, and a collection of art and antiquity.
The abbey of St. Maurice is built on the ruins of a Roman shrine of the 1st century B.C. dedicated to the god Mercury in the Roman staging-post of Agaunum. According to Eucherius, Bishop of Lyon, around 370, Theodorus, Bishop of Valais, constructed a small shrine to commemorate the martyrdom of St. Maurice and the Theban Legion, which was said to have occurred in the area where the abbey is located. Theodorus then gathered the local hermits in a common life, thus beginning the Community of Saint-Maurice.
In 515, the Basilica of St. Maurice of Agaunum became the church of a monastery under the patronage of King Sigismund of Burgundy, the first ruler in his dynasty to convert from Arian Christianity to Trinitarian Christianity.
The abbey is a Swiss heritage site of national significance. |
