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 design, the royal castles and coats of arms are arranged in a cross formation, symbolising the consolidation of the Portuguese territory and the foundation of the kingdom. Surrounding these heraldic elements are the seven castles and five shields, which represent the historical conquests and the lineage of the first kings of Portugal. This iconography serves as a permanent emblem of the country's sovereignty and its long-standing cultural heritage within Europe. The coin was issued in 2004 with a mintage of 1,000,000 pieces.
