The Portuguese 2 euro standard circulation coin features a design rooted in the nation’s deep historical identity, showcasing the royal seal of 1144. At the centre of the national side, the design displays the five shields, known as the quinas, arranged in a cross formation. These are surrounded by seven castles, representing the fortified towns conquered by King Afonso Henriques during the formation of the Portuguese kingdom. This heraldic motif serves as a symbol of national sovereignty and the endurance of the borders established in the twelfth century. The surrounding stars of the European Union frame the composition, reflecting Portugal’s integration into the modern continent while maintaining its distinct historical heritage. This standard issue coin was minted in 2015.
