 note = {Surveys have been conducted in Hagia Sophia since 2009 and a new phase of our survey was launched in 2013 as a component of a large project, “Documentation, Analysis and Conservation of the Historical Architecture in Turkey.”
 In Hagia Sophia,deterioration of the walls has accelerated owing to rainwater infiltration from the outside and evaporation on the inside surface.Additionally,crystallization is caused by water and salt movement in the porous materials, and it changes depending on the season.
 At the North and South Tympanum,the use of pigment containing lead was confirmed: in the yellow pigment at the North Tympanum, and in the white pigment at the South Tympanum.
 Survey has been started in Aya Irini since 2013 and it has been observed that crystallization at the second floor is also mainly caused by rainwater infiltration from the outside.
 A new survey has also started in Kariye in 2014 and it has been observed that crystallization at the bottom part of some mosaics is especially caused by exposure of the setting bed and the incoming of air from the door in exonarthex.},
