10 Euro Silver Coin – Hellbrun Castle | Schloß Hellbrun (2004)
Castles of Austria Series (2002-2004)
The Castles of Austria Series ran from 2002 to 2004 and featured a total of six coins. Each coin in the series, released two a year, depicts a famous Austrian castle and is struck in 0.925 fine silver. The coins are legal tender in Austria at a face value of 10 euros and come in three finishes: Uncirculated, Special Uncirculated, and Proof. The Special Uncirculated version was issued in a limited edition bi-fold card, which houses the coin in a blister pack. Proofs were issued in numbered editions, contained in a plastic capsule and housed in a burgundy box. The Hellbrun Castle (2004) 10-euro silver coin was the fifth issue of the series.
Hellbrun Castle was constructed 400 years ago by Italian architect Santino Solari (1576-1646). The palace was a high-watermark, figuratively speaking, for baroque architecture in the Austrian Alps. Built as a daytime pleasure house for Mark Sittich von Hohenems, the Prince-Archbishop of Salzburg from 1612-1619.
Beyond its baroque influences, the edifice and its grounds are playful and represent the Archbishop’s sense of humor. Numerous “tricks” and curiosities sprinkle the grounds–and quite literally, even some of his “honored” guests.

A courtyard view of the façade of Castle Hellbrun, the Alpine mountain Unterburg carves out a rugged skyline in the distance. The inscription REPUBLIK ÖSTERREICH arches along the top of the coin next to the rim. In the exergue: SCHLOSS HELLBRUN, 10 EURO, and the date 2004. The artist’s signature H. WÄHNER is located next to the rim at the nine o’clock position.

A scene of the palace grounds. Depicted in the foreground is the Archbishop. He is pointing at an architectural painting of Hellbrun in a manner that is adapted from his 1618 portrait “Markus Sittikus, Erbauer des Schlosses Hellbrunn” by Italian painter Arsenio Donato Mascagni (1579-1636). In the background is the Hellbrun “Roman Theater”, Sittikus’ playful architectural tribute to Roman Emperor Marcus Aurelius, complete with fish pond, fountain and statuary. The designer’s initials TP are visible on the ledge of the fountain near the rim at the nine o’clock position. An inscription reads ERZBISCHOF MARKUS SITTIKUS 1612-1619.
