List of medieval buildings in Belgium, Denmark, Germany and the Netherlands in which volcanic tuff of the Eastern Eifel Area of Germany was used. The list contains 1108 buildings, mainly churches but also secular building like fortifications and residential buildings.Until now there had been some regional studies about churches built with this material, but no compehensive list or map covering the whole distribution area. The presented list and the map based on the list is an attempt to present the first comprehensive transnational representation of the medieval use of tuff from the Eastern Eifel. The list provides the positions of the buildings representetd in WGS 84 (EPSG 4326), monument-IDs, where applicable, and some other basic information.
