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 displays one of the oldest seals of the country, dating back to 1144. This intricate emblem is surrounded by seven castles and five shields, which represent the historic fortifications and the legendary five wounds of Christ, respectively. These symbols are arranged within a circle of stars, reflecting Portugal's integration into the European Union. The design serves as a permanent tribute to the foundational era of the Portuguese monarchy and the consolidation of its borders during the twelfth century. This standard issue was released in 2007.
