Depicts Gates of Belvedere and Upper Belvedere Palace encircled by the facial value, heraldic hatchings representing the Austrian flag, date and the twelve stars of Europe.

The Belvedere is a historic building complex in Vienna, Austria, consisting of two Baroque palaces (the Upper and Lower Belvedere). The buildings are set in a Baroque park landscape in the third district of the city, on the south-eastern edge of its centre. The grounds are set on a gentle gradient and include decorative tiered fountains and cascades, Baroque sculptures, and majestic wrought iron gates. The Belvedere was built during a period of extensive construction in Vienna, which at the time was both the imperial capital and home to the ruling Habsburg dynasty. This period of prosperity followed on from the commander-in-chief Prince Eugene of Savoy's successful conclusion of a series of wars against the Ottoman Empire.

The Austrian State Treaty re-established Austria as a sovereign state. It was signed on 15 May 1955 in Vienna, at the Schloss Belvedere among the Allied occupying powers (France, the United Kingdom, the United States, and the Soviet Union) and the Austrian government.

A geographical map of Western Europe spans the outer ring and inner core on the left side of the coin.

12 stars are located on the left side of the outer ring, with six stars atop the map of Europe and six stars below it; six vertical stripes cut across the inner core of the coin, visually connecting the upper and lower star segments.

Luc Luycx, a designer at the Royal Belgian Mint, designed the Euro’s common reverse; his initials, LL, are seen on the right side of the design, just under the “0” in “20.”
