Welcome!
I work with the geoarchaeology of old stone: quarries, monuments, rock art. And I try to figure out about their weathering, and conservation using traditional crafts. I also burn lime the traditional way. Many of my domestic services are managed through FABRICA, a registered Norwegian company established with good partners. On this website I publish articles on geology and cultural heritage. For the joy of old stone! Per Storemyr

Forvitring av kleberstein på middelalderkirker – to videoer
Sist vinter holdt jeg to foredrag om forvitring av kleberstein sett i lys av bygnings- og restaureringshistorie. Det dreide seg om portaler fra norsk middelalder og foredragene ble holdt på «Portalseminaret» i regi av «Domkirken 2025»; miljøet som nå restaurerer Stavanger domkirke og som jeg også er en liten del av. Alle foredragene fra seminaret (og mange andre interessante saker om restaureringen) er nå lagt ut på YouTube.
Kanskje kan mine to foredrag være til hjelp for folk som sliter med å forstå hvorfor kleberstein forvitrer. Veldig mye dreier seg om hva bygningene har vært utsatt for av forandringer og restaureringer gjennom tidene. Men noe av forvitringen kan også knyttes til steinkvalitet, tidligere luftforurensning og ikke minst vann! Rett og slett lekkasjer! Innholdet i foredragene er i stor grad basert på min gamle doktoravhandling “The Stones of Nidaros” fra 1997 og mange artikler om forvitringshistorie, bl.a. “Weathering of soapstone in a historical perspective”.

Good stone doesn’t change its location!
There have been few new posts on my blog recently. But there is a very good reason for this apparent laziness, since I’m now writing a book about stone. Or, to be more correct, a book about the cultural history … Continue reading

Experimental archaeology: The traditional way of quarrying soapstone
Experimental archaeology in old building stone quarries is a rare activity. But not so for Norwegian stone carver Eva Stavsøien. She asked herself how soapstone was extracted in the Middle Ages. Bringing handmade pickaxes, she went to an abandoned quarry … Continue reading

Where does the stone at Nidaros Cathedral come from?
Stone to the northernmost of Europe’s great cathedrals was provided from no less than 50 different quarries across Norway and to some extent from elsewhere in Europe. But there are great differences between the medieval building period (11th to 14th … Continue reading
