Pope Leo XIV visited the Sultan Ahmed Mosque in Istanbul today, also known as the Blue Mosque.
The Roman Catholic leader, unlike his predecessor, Pope Francis, did not pray during his 2014 visit.
On the third day of his visit to Turkey, the first American pope in history toured a 17th-century mosque accompanied by the Grand Mufti of Istanbul.
In the afternoon, the Pope will participate in a prayer service at the Church of Saint George before joining Ecumenical Patriarch Bartholomew I at the Patriarchal Palace on the shores of the Golden Horn.
They will sign a joint declaration, the contents of which have not been disclosed.
Pope Leo XIV will end the day with a mass at the Volkswagen Arena in Istanbul, where around 4.000 faithful are expected.
