Salt weathering is one of the main causes of decay of natural stone, and by consequence a major problem to the conservation of cultural heritage. In the present case, the performance of Morley limestone from the Département Meuse, France, as a replacement stone under saltloaded conditions is evaluated. Morley limestone was used in the Netherlands as a replacement stone for sandy Eocene Belgian limestones (Gobertange, Lede).

Key words: Morley limestone, salt weathering, Pieterskerk, Leiden
