President Obama will tour two of Turkey's most historic mosques before leaving Europe, the White House announced Monday.

Obama will join Turkish Prime Minister Tayyip Erdogan on a tour of the Hagia Sophia and the Sultan Ahmed Mosque (a.k.a., The Blue Mosque). The Blue Mosque is the national mosque of Turkey.

The move represents a symbolic gesture for Obama, who has made outreach to the Muslim world an early emphasis in his presidency and in his trip abroad to Europe.
