Castillo de Coca

Castillo de Coca is the finest example of Mudéjar brickwork in Spain, built in the 15th century using over 1 million handmade bricks. Its walls are 2.5 meters thick and taper to a 1-meter width at the top, creating a striking silhouette. The brick construction makes it 40% lighter than the stone-built Alhambra (item #1), yet its defensive ditches and 15-meter-tall towers remain imposing. No other Spanish castle uses this technique so consistently.
