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

Soapstone in the Far South of Norway (II): The Østre Vimme Multiperiod Quarry With Very Soft Soapstone
Østre Vimme is another of the several old soapstone quarries in the Aust-Agder region of Southern Norway. It was worked in the Iron Age for «standard» vessels, but it has at least three production phases, for which there may be a specific reason: Parts of the quarry feature very talc-rich and soft soapstone, implying that the stone was also easy to carve for small items like spindle whorls, sinkers and lamps. Hence, it would have been a valuable resource for a long time. Softness may be the result of a special geology. Dutch geologists have suggested that this is a deposit not derived from alteration of ultramafic rocks, which is by far most common mode of formation in Norway. Rather, it may derive from alteration of dolomitic limestone. There is only on other known soapstone deposit in Norway with such an origin. Here’s an account of this exciting quarry, also including a discussion of whether soapstone vessels from the quarry were exported to Denmark in the 9th century CE. Continue reading
Soapstone in the Far South of Norway (I): The Sparsås Iron Age Quarry
The region of Aust-Agder in Southern Norway hosts a range of Iron Age soapstone vessel quarries. One of them, the Sparsås quarry in Froland, is exceptionally well-preserved and one of the most “classic” quarries I have ever visited in Norway. With unfinished vessel blanks still attached to the quarry faces and a highly organised layout of the spoil heaps, it once must have been worked in an efficient way, providing vessels and other items for regional use and, quite probably, for export to Denmark and beyond. Here’s an account of the research history, geology and layout of the quarry. A hypothesis is also offered: This was a short-lived quarry, operated for a generation or so within the 9th or 10th century CE. Continue reading
Moster gamle kirke: Middelalderkirken som ligger midt i et steinbruddslandskap
Ingen annen norsk middelalderkirke ligger så velplassert midt i et gammelt steinbruddslandskap som lille Moster gamle kirke på Bømlo. Det er vanskelig for den utrente å se i dag, men omkring kirken ligger det ikke mindre enn sju steinbrudd innen … Continue reading

Ny base på Sørlandet!
Jeg har nettopp flyttet med min familie til Arendal og dermed har jeg ny base på Sørlandet for tjenester til kulturminnevernet. Det betyr også at jeg nå bor nærmere Fabricas «hovedkontor» på Vøienvolden i Oslo. Som kjent går oppdrag innen … Continue reading

Steinmysteriet i Stavanger domkirke. Hvor kommer klebersteinen i koret fra?
I mer enn 20 år har jeg fundert på hvor klebersteinen til byggingen av koret i Stavanger domkirke kommer fra. Jeg har trålet Rogalands kleberforekomster. Jeg finner ingen svar, og ingen andre gjør det heller. Koret ble bygd i gotisk stil på slutten av 1200-tallet, etter en brann i kirken. Koret har en svært karakteristisk kleberstein – en stein vi kaller «Stavangerkleber». I en tid har det vært spekulert på, med meg selv som bidragsyter, om bruddet på Vestre Åmøy nord for Stavanger kanskje kunne være kilden. For noen dager siden tok jeg nok en tur til bruddet – og kan avkrefte: Dette er nok ikke bruddet for Stavangerkleber. Så hvor kommer den fra? Continue reading

Selja kloster: På leit etter kildene til den beste muresteinen
Mange ser bare gråstein. Men Selja kloster har en variert «geologi» som kan fortelle mye om hvordan folk organiserte byggearbeid i middelalderen. Hvor fant de sine byggestein? Sammen med Bjørn Jensen og andre har jeg i flere år lett etter steinbruddene til anlegget. Det har dukket opp atskillige brudd og samleplasser for stein på klosterøya. Men vi har ikke funnet alle kilder til det ypperlige murverket fra romansk tid. Vi snakker om murestein, gneis som fra naturens side spalter i regelmessige, passe store blokker – og som ble benyttet i titusenvis på Albanustårnet og den svære terrassen. Så vi begynte å lete på Stadlandet. Og der fant vi ikke bare tørrmurte steinkonstruksjoner fra senere tider, men også en godbit av et steinbrudd. Continue reading

Partner in the Borgund Kaupang Project – on the rise and fall of a medieval town
My company is proud partner in the Borgund Kaupang Project (2019-2023), on the rise and fall of a “lost” medieval town. The project is coordinated by the University of Bergen and financed by the Norwegian Research Council. Together with Alf Tore Hommedal, my task is to source building materials such as marble, soapstone and lime for mortar and to interpret the whole building process, from quarries to churches. Thanks a lot to project manager Gitte Hansen, Therese Nesset and a great international team for a fine kick-off meeting in Ålesund last week! Continue reading
