What unites such dissimilar monuments as Chartres Cathedral, the terracotta army of the first Chinese emperor, the Egyptian pyramids, the temple in Jerusalem, the Grand Canyon in the West of the USA, Iguazu Falls in South America, the cathedral in Aachen and the wooden churches of Norway? All of them belong to the cultural heritage of mankind and are taken under protection by UNESCO in order to preserve them for the peoples of the world. Only current generations have recognized the need for their own participation in this defense. We can understand our roots only by studying traditions passed from century to century, feeling the meaning of intact nature.
