Basilica of the Holy Cross of the Valley of Cuelgamuros (Valley of the Fallen), Madrid, Spain: The Basilica of the Holy Cross of the Valley of Cuelgamuros, near Madrid — an immense architectural feat carved into the granite mountainside and crowned by a 150-meter cross, one of the tallest in the world. Designed by architects Pedro Muguruza and Diego Méndez, it was built between 1940 and 1959 under Franco’s regime as a monumental memorial to those who died in the Spanish Civil War. Today, it is a striking and controversial symbol of Spain’s 20th-century history and collective memory.
