Cathedral de Sal - Zipaquira, Cundinamarca. Definitly a piece of art! His cathedral in a salt mine at 180m under the earth, would not be anything without the illumination who give to it its majestic aura! Red, blue, green and white, represent: earth, heaven, hope, and Spirit of God. Even if you are not Catholic, or even Christian, you should come. Come and be transported into another world! The Columbian People are great God Loving Folk! Great Artist!
