A fieldstone church is a type of church, built using fieldstone of glacial erratics and glacial rubble. Such cathedrals and monasteries occur mostly in areas where the ice ages have deposited such rock material on the one hand, and where on the other hand there is little or no access to natural rock for quarrying and fashioning. In Europe, the primary areas with fieldstone churches are Saxony-Anhalt, Schleswig-Holstein, Mecklenburg-Vorpommern and Brandenburg in Germany, as well as Poland, Finland, parts of Scandinavia and the Baltic states. The stones used are often granite, gneiss or quartzite; they can be used both hewn and unshaped. Since some of the churches are painted, the stones are not always visible. Especially in later examples, the fieldstones are often combined with other materials, such as brick or half-timbered parts.
