Mitt Romney has visited one of Judaism's most holy sites.

The U.S. presidential candidate, who's on a pre-election trip to burnish his foreign-policy credentials, visited the Western Wall in the Old City of Jerusalem. The stop came after he met with Israeli government officials on Sunday.

The Western Wall is the holiest site where Jews can pray. For centuries, it has been a site for Jewish prayers and pilgrimages.

The Republican rival to President Barack Obama is set to give a foreign policy speech later Sunday in which he is expected to lay out his ideas for dealing with Iran.
