This paper presents an analytical study of the deterioration and degradation phenomena of two
overlaid wooden doors from Ottoman period caravansaries: (A) Hassan Pasha caravansary- X
century BC - XVI century AD and (B) Ibrahim Sarhan caravansary- X Century BC- XVI Century
AD in Bulaq, Cairo, Egypt. To identify the deterioration and degradation in the types of wood
used, microbiological study, Scanning Electron Microscopy coupled with X-ray Energy
Dispersive (SEM-EDX), X-ray Diffraction (XRD) were conducted. The data obtained were used
to evaluate the status of conservation of overlaid wooden doors (wood and Iron) and to identify
the suitable treatment methods. parts.
