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 Federal Palace of Switzerland.
The Federal Palace is a building in Bern housing the Swiss Federal Assembly (legislature) and the Federal Council (executive). It is the seat of the government of Switzerland and parliament of the country. The building is a listed symmetrical complex just over 300 metres (980 ft) long. It is considered one of the most important historic buildings in the country and listed in the Swiss Inventory of Cultural Assets of National Importance. It consists of three interconnected buildings in the southwest of Bern's old city. The two chambers of the Federal Assembly, the National Council and Council of States, meet in the parliament building on Bundesplatz.
The oldest part of the Federal Palace is the west wing (then called "Bundes-Rathaus", now "Bundeshaus West"), built from 1852 to 1857 under Jakob Friedrich Studer. The building united the federal administration, government and parliament under one roof. To solve pressing space problems, the east wing ("Bundeshaus Ost") was built from 1884 to 1892 under Hans Wilhelm Auer. Under Auer's direction, the parliament building in the center was erected between 1894 and 1902 to conclude the project. |
