Google's machine translation is a useful starting point for translations, but translators must revise errors as necessary and confirm that the translation is accurate, rather than simply copy-pasting machine-translated text into the English Wikipedia.
Do not translate text that appears unreliable or low-quality. If possible, verify the text with references provided in the foreign-language article.
Formerly a mining area, now its economy is based on agriculture and emerging tourism. The tourism is based on the area's beauty and historical interest. The peak Sobia is distinguished by its impressive vertical walls of limestone and its flat top. The collegiate church of San Pedro, in a high medieval style, dates from between 1069 and 1076. One can explore the mountains and the 12-km long Huerta Cave, the Senda del Oso bicycle path, or a museum of prehistory.
