Castillo Colomares (Colomares Castle) at Benalmadena Pueblo, Spain pays homage to Christopher Columbus and his discovery of America. Its beautifully kept gardens complement the Byzantine, Roman, Gothic and Mudejar architecture perfectly. Built by Esteban Martin and two stonemasons from nearby Mijas, it took from 1987 to 1994 to create this masterpiece.
The Diquis Spheres Known locally as Las Bolas, the spheres range in size from a few centimetres to over two metres in diameter, and weigh up to 16 tons. Most are sculpted from gabbro, the granitic equivalent of basalt. There are a dozen or so made from shell-rich limestone, and another dozen made from a sandstone. The stones are believed to have been carved between 200 BC and 1500 AD.
