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

Om «Soknakrossen» på øya Sokn i Rogaland. Steinkrossen kom nok fra Hyllestad!
Her forleden var jeg på vandring på øya Sokn i Rogaland (mellom Stavanger og Rennesøy). Vest på den vesle øya, med formidabel utsikt mot havet, finnes et sted kjent som «Soknakrossen», rett ved en massiv gravrøys fra bronsealderen. Så vidt jeg vet er det først og fremst Fridtjov Birkeli som i mer moderne tid har beskrevet stedet og korset – i sitt verk om «Norske steinkors i tidlig middelalder». Steinkorsene var store maktsymboler langs vestlandskysten og markerte ikke minst overgangen til kristendommen i Norge. Continue reading

Selja kloster: Hvor kom middelalderens kalkmørtel fra?
Det har en stund vært kjent at hvit og fin marmor ble brent for å lage kalkmørtel til byggingen av Selja kloster i middelalderen. Men hvor ble det brent? Hvor kommer marmoren fra? Her ute i havgapet, langt vest i Norge, er det ingen marmorforekomster. Man må til Sunnmøre eller Bergenstraktene for å finne marmor. Til marmor på Sunnmøre er det ikke langt, bare 20 km i luftlinje. Men i veien står Norges farligste hav, Stadhavet. I middelalderen ble bygningsmaterialer fraktet med båt! Turte man å gå 50-60 km på dette farlige havet, attpåtil med ytterst farlig brentkalk i lasten? Fraktet man heller ubrent kalk? Eller tok man heller den lange turen sørfra, mer enn 250 km? Vi har ennå ikke svaret, men med undersøkelser innen Riksantikvarens bevaringsprogram for ruiner begynner vi å nærme oss. Continue reading

Tjenester for kulturminnevernet: Hva gjør en geoarkeolog for steinbygninger, steinbrudd og bergkunst?
Mange spør meg: Hva driver du med? Hvilke tjenester tilbyr du? Jeg er geoarkeolog og jobber med rådgivning og forskning knyttet til gamle steinbygninger, steinbrudd og bergkunst, svært ofte i forbindelse med restaurering, konservering og arkeologiske utgravninger. Under skal jeg … Continue reading
The limekiln at Hyllestad, Western Norway: Rebuilding a new, “historic” kiln for burning lime
Last year we built a limekiln at Millstone Park in Hyllestad, Western Norway, reported on this website. The kiln was built in a traditional fashion, following Roman and Medieval principles. Experimental archaeology! After one burn, which gave excellent quicklime, the kiln was, unfortunately, badly damaged. Cracks in the masonry! So we had to rebuild the kiln to be able to produce more quicklime! Over the last few months a team of professional, Norwegian masons and local volunteers, 15 people altogether, has undertaken the task: Just a little more work to be done, and soon we’ll have two(!) limekilns, one big and one small – for producing “historic” quicklime in the years to come. For restoring old stone buildings.
Below, you will find a report of the rebuilding, written in Norwegian. Use Google Translate if you are not familiar with the language. The report is written by me and was first published on the website of Millstone Park (kvernsteinsparken.no) a couple of days ago. I work part-time as an Associate Professor for Millstone Park and I am project leader and responsible for building, rebuilding and running the limekiln. Great combination of craft and theory, experimental archaeology! But I’m also involved, privately and through my company, Archaeology & Conservation Services, as a local volunteer. Building and running a historic limekiln is a very big task, many months of work for many people! And though the Norwegian Directorate for Cultural Heritage is a generous sponsor of the project, voluntary work is indispensable. Thank you all! And here’s the report, with many videos and photos: Continue reading

The world’s northernmost medieval marble church
The small, Romanesque Gildeskål church is one of the most complete marble churches in Norway. It resides at the magnificent coast along the Atlantic Ocean far up north, in Nordland county. And it is, presumably, the northernmost marble building in the world. Together with Giske church further south, it is part of outstanding, but little known, medieval marble architecture in Norway, of which Nidaros Cathedral, with thousands of marble columns, is the most spectacular example.

Burning the beaches. Happy New Year from the Faroe Islands!
The Faroe Islands, in the middle of the North Atlantic Ocean. Basalt and other volcanic stone everywhere! Yet, many buildings on the islands were erected by the use of lime mortar, from the Middle Ages on. There is absolutely no limestone on the Faroes. Thus, lime mortar had to be produced by “burning the beaches” – collecting shells from beach deposits, stacking the shells above a fire in a field kiln – and let it happen: Hold the temperature at some 900 degrees centigrade for a couple of days, and out comes quicklime to be mixed with water and beach sand for the mortar. Continue reading

Værnes: Norges mest komplette sandsteinskirke fra middelalderen
Den er dekorert med elementer av kleberstein og klorittskifer, men ellers er det sandstein så langt øyet kan se: Værnes er Norges mest komplette sandsteinskirke fra middelalderen! Den rager i størrelse og volum av brukt sandstein langt over middelalderbyggverk i tilsvarende stein i andre deler av landet! Her er et sammendrag av min artikkel til boken «Værnes kirke – en kulturskatt i stein og tre» som ble utgitt for et par uker siden (november 2016). Det er Grubleseminaret som står bak, med Morten Stige og Kjell Erik Pettersson som fantastiske redaktører av boken! Continue reading

New open-access book: Soapstone in the North. Quarries, Products and People. 7000 BC – AD 1700
NEW BOOK: Hansen, G. & Storemyr, P. (eds.) 2017. Soapstone in the North: Quarries, Products and People. 7000 BC – AD 1700. UBAS University of Bergen Archaeological Series, 9, 408 p. Abstract: “Soapstone is a remarkable rock. While it is soft and very workable, it is also durable and heat-resistant, and with a high heat-storage capacity. These properties have been recognised and valued around the world since prehistoric times, and soapstone has been used for a multitude of purposes, ranging from everyday household utensils to prestigious monuments and buildings. This book addresses soapstone use in Norway and the North Atlantic region, including Greenland. Although the majority of the papers deal with the Iron Age and Middle Ages, the book spans the Mesolithic to the early modern era. It deals with themes related to quarries, products and associated people and institutions in a broad context. Recent years have seen a revival of basic archaeological and geological research into the procurement and use of stone resources. With its authors drawn from the fields of archaeology, geosciences and traditional crafts, the anthology reflects cross-disciplinary work born of this revival.” Continue reading
