The design features the keep of the Varaždin Castle (12th – 16th century). Varaždin is first mentioned in 1181. Having suffered massive casualties in the Tatar invasion of 1242, it was built as a royal fortress, which would become known as the Old Town. Its appearance has changed through the centuries: from a strong medieval fortress surrounded by water-filled moats to the main fortress and armoury of Slavonian Military Border and Varaždin military headquarters and a beautiful Renaissance castle. At present, the Old Town is the most important and magnificent historical building of the City of Varaždin, a highest-category monument of the Croatian architectural heritage. The coin also features the name of the issuing country ‘HRVATSKA’ (Croatia), the year of issuance ‘2024’, and the words ‘STARI GRAD VARAŽDIN’ (the Old Town of Varaždin), which are all inscribed circularly at the top and the bottom of the design. The coin’s outer ring bears the 12 stars of the European flag. (Source: ecb.europa.eu)
