唐大中三年（849 年）收复，为原州治。广明元年（880 年）复没于吐蕃①。治所在今宁夏固原县西南四十里②。
①《新唐书》卷37《地理一》原州条：“大中三年收复关、陇，归治平高。广明后复没吐蕃”，中华书局1975 年版，第968 页。
②《读史方舆纪要》卷58《陕西7》平凉府开城（段案：应为“成”）废县条：“州西南四十里。汉安定郡高平县地。唐亦为高平县地，属原州。宋置开远堡，属镇戎军。元置开成路及开成县于此，寻降为州。明初改为县。景泰中议者言开成东北四十里有固原州城，修筑置戍，足以固边折寇。乃命修筑。成化三年，寇破开成，因徙县于固原。弘治中，改置固原州，而以开成县省入焉。”中华书局2005 年版，第2804 页。    ]]>  </source-note>  <source-uri>      </source-uri></placename>
