A total solar eclipse will sweep across the Northern Hemisphere on Wednesday, Aug. 12, marking the first total eclipse visible from mainland Europe since 1999 and offering millions of people across multiple continents a chance to witness the moon completely block the sun. Notably, this will be the first total eclipse visible from Iceland since June 30, 1954, and the first visible specifically from Reykjavik since 1433, underscoring the rarity of the event for residents there. SpainSpain stands as the other major hub for eclipse tourism this year, given its accessibility and status as the first place on mainland Europe to experience a total solar eclipse since 1999. Roughly the entire northern half of the Iberian Peninsula will experience totality, while the southern half will see only a partial eclipse. Spain's total solar eclipse marks the first such event visible from the Iberian Peninsula in more than a century.
