The 2017 Spain 2 euro commemorative coin honours the Churches of the Kingdom of Asturias, a collection of pre-Romanesque monuments recognised as a UNESCO World Heritage site. The national side features a detailed depiction of the Santa Maria del Naranco, a prominent example of Asturian architecture located on the slopes of Mount Naranco near Oviedo. Constructed in the 9th century, this structure serves as a testament to the artistic and cultural legacy of the Asturian monarchs who played a pivotal role during the Reconquista. By highlighting this architectural heritage, the coin celebrates the historical significance of Northern Spain in the development of medieval European art and religious building styles. This issue was released into circulation in 2017 with a mintage of 4,000,000 coins.
