The construction material predominately used for the tombs at the Bartholomew Cemetery is the highly porous Buntsandstein. Different types of damage and stress-strain phenomenon is evident 264on the stones (Fig. 1). They range from locally-formed holes to finely sanded surfaces, crack formation, flaking and crusts. The analyses show that in large part the material loss is due to the high salt accumulation resulting in salt crystallization (Kracke et al. 2007).
