I work with the geoarchaeology of old stone: quarries, monuments, rock art. And I try to figure out about their weathering and conservation. My domestic services are managed through FABRICA, a registered Norwegian company established with good partners. On this website I publish articles on heritage. For the joy of old stone! Per Storemyr

But underground quarries are, interestingly, quite rare in the European Middle Ages. Apparently, there was no need to start difficult, large-scale underground operations to build churches, monasteries and cathedrals until the Late Middle Ages, when, for example, the underground limestone quarries in Paris and Caen in France started to become developed toward the gigantic network of tunnels and galleries we know today. Thus, it is remarkable that a huge underground quarry may have been opened around AD 1200 in Trondheim, Norway, in order to provide soapstone for Nidaros Cathedral, the northernmost of Europe’s great medieval cathedrals.
