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 features the Munot Fortress in Switzerland.
The Munot is a circular 16th century fortification in the center of the Swiss city of Schaffhausen. It is surrounded by vineyards and serves as the city's symbol. The ring-shaped fortress was built in the 16th century. Today, it is a tourist attraction and hosts various events.
Earliest presence of a castle dates to 1379. The current complex was built between 1564 and 1589 under the city master builder Heinrich Schwarz , probably to the knowledge of Albrecht Dürer's work of a circular fortification. It is one of the few examples of the transition from a castle to a modern Fortress.
The Munot was part of the city fortifications. The construction cost the city 47,528 guilders, which corresponded to the construction costs of around 800 townhouses. |
