The Portuguese 2 euro standard circulation coin features a design deeply rooted in the nation's historical identity and royal heritage. At the centre of the national side, the coin depicts the royal seal of 1144, surrounded by the seven castles and five coats of arms that represent the foundation of the Portuguese kingdom. These symbols are arranged in a circular pattern, interspersed with the letters of the country's name, 'Portugal', and the year of issue. The design serves as a tribute to the consolidation of the country's borders and the establishment of its monarchy under Afonso Henriques. This heraldic motif reflects the enduring sovereignty of Portugal throughout the centuries. The coin was issued in 2021.
