西班牙纳瓦拉Bardenas Reales的Castildetierra(Castildetierra in the Bardenas Reales, Navarre, Spain)

在西班牙纳瓦拉Bardenas Reales的中心地带，一片独特的半沙漠景观，耸立着该地区最具标志性的岩层Castildetierra。它的轮廓让人想起一座被风和水侵蚀的天然塔，是联合国教科文组织宣布为生物圈保护区的这片领土的象征。

In the heart of the Bardenas Reales of Navarre, a unique semi-desert landscape in Spain, rises Castildetierra, the most iconic rock formation in the area. Its silhouette, reminiscent of a natural tower eroded by wind and water, is a symbol of this territory declared a Biosphere Reserve by UNESCO.
