ABSTRACT
The ultrasonic velocity method is an in situ, NonDestructive technique which is used for the evaluation of surface conditions on historical monuments, without receiving testing materials. The results give the opportunity of recording and evaluating data, consisting major factors of quality and weathering of the surfaces. The implementation of this method took place in one of the most impressive monuments in the Aristotle University of Thessaloniki. This tomb dates in the first quarter of 4th century and belongs to a member of Israelite com-
munity in Thessaloniki and was founded in university campus between the central administration building and the building of Law and Economic Sciences. It is about a well-preserved historical monument with favorable position for taking the ultrasonic measurements, (Marki E., 2001).
