This study is on the some anatomical, physical and mechanical properties of the Carob (Ceratonia siliqua L.) grovvn naturally in the mediterranean region of Turkey. The physical properties were: 1) ovendry density 0,81 g/cm3; 2) air dry density 0,86 g/cm3; 3) density value in volüme 0,71 g/cm3; 4) radial shrinkage 4,39%; 5) tangential shrinkage 8,01%; 6) radial swelling 4,5%; 7) tangential swelling 8,84%; 8) maximum moisture content 73,38%; 9) percentage of celi wall 54,22%; 10) percentage of porosity 45,87% and 11) fiber saturation point 17,41% . The mean values of the mechanical properties are given belovv. Bending strength 122,05 N/mm2, modulus of elasticity in bending 11458,35 N/mm2, impact bending 1,43 kpm/cm2, compression strength paraleli to grain 66,63 N/mm2, tensile strength perpendicular to grain 5,192 N/mm2, cleavage strength (in radial direction) 1,207 N/mm2, janka hardness on cross section 109,83 N/mm2, radial section 91,5 N/mm2, tangential section 85,18 N/mm2, static quality value 7,73 and dynamic quality value 2,18.
