The Belgium 2023 2 euro commemorative coin celebrates the Year of Art Nouveau, an architectural and decorative movement that flourished in Brussels at the turn of the 20th century. The national side features a detailed architectural motif inspired by the iconic curves and organic forms characteristic of the style, reflecting the city’s status as a global centre for this aesthetic innovation. By highlighting these intricate patterns, the design pays homage to the visionary architects who transformed the urban landscape of Belgium through fluid lines and natural motifs. This commemorative issue serves as a tribute to the enduring cultural legacy of the Art Nouveau movement within the country's historical heritage. The coin was issued in 2023 with a mintage of 150,000 pieces.
