"Correction: March 7, 2015
An earlier version of this article misstated the age of the Hatra archaeological site. It dates to the first century B.C., not the 12th. The same error appeared in an earlier version of a picture caption and a capsule summary with this article. The earlier version also misidentified the location of a statement by the Ministry of Tourism and Antiquities. It appeared on the ministry’s website, not on its Facebook page."
