Did french fries and Irish potato come from coastal region of Spain?

French fries and the Irish potato did not originate from the coastal region of Spain. French fries are believed to have originated in Belgium, while the Irish potato, specifically the variety known as the Irish or white potato, was introduced to Ireland from the Andes region of South America in the late 16th century. Potatoes were brought to Europe by Spanish explorers, but their cultivation and popularization occurred in various countries, including Ireland.
