Toledo Cathedral (Catedral Primada Santa Maria de Toledo) is Spain's paramount Gothic masterpiece, a stunning blend of French Gothic architecture and Spanish flair, famous for its immense size, gilded High Altarpiece depicting Christ's life, the magical light of the Baroque "Transparente," and a sacristy housing masterpieces by El Greco (like The Spoliation) and other Spanish masters, making it a treasure trove of art and history reflecting Toledo's rich religious tapestry.
