Cl PA 2003 XIX th International Symposium, 30 September - 04 October, 2003, Antalya, Turkey 
The layers of dust and soot on the stone panels resulting from 
atmospheric pollution were also indicated on the survey 
drawings to determine the method, area and locations of stone 
cleaning necessary. 
4.4 Colour Analyses 
Colour analyses had to be carried out in order to determine 
original colours used in the painted decorative programme 
(,kalemifi) on the ceiling surfaces. PANTONE Process Colour 
System and PANTONE Colour Specifier catalogues were used 
to determine the colours of the existing decorations and were 
indicated on the 1:1 scale survey drawings for restoration. 
5. RESTORATION METHODOLOGY AND 
EVALUATION 
The aim of the evaluation of the data obtained through the 
survey and documentation process was the undoing of the 
damage due to the earthquakes of Kocaeli on August 17, 1999 
and Diizce on November 12, 1999 through a minimal 
intervention focusing on structural strengthening, preserving the 
original architectural, structural and material characteristics of 
the building. The suggested method of restoration would not 
only reinstate the original appearance of the building, which has 
been changed through a series of inappropriate interventions 
following major earthquakes but would also enable it to survive 
future earthquakes with minimal damage. Following its 
restoration, the building must be re-opened to the public with an 
undemanding function that would enable lengthening its life 
span through proper maintenance.
