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

Ny rapport: En studie i saltforvitring når klimaet forandrer seg: Albanustårnet på Selja kloster 2016-2020
I 2016 ble et forskningsprosjekt om saltforvitringen i Albanustårnet på Selja kloster startet opp. Nå foreligger sluttrapporten fra prosjektet. Det har vært utført sammen med Selje, senere Stad kommune, og Riksantikvaren og ble avsluttet i vår av Fabrica kulturminnetjenester, etter at mitt eget firma ble knyttet til Fabrica i 2019. Rapporten beskriver i detalj hvordan forvitringen foregår i middelaldertårnet og gir også en analyse av mulige bevaringsstrategier. Arbeidet kan være til nytte også for andre steinbygninger som sliter med saltforvitring, spesielt langs kysten. Her er sammendrag og link til den åpne rapporten. Continue reading
Mange har meninger om frostforvitring på kulturminner, på stein, murverk, puss og mørtel. Men det er få som har dokumentert fenomenet med bilder. Derfor er det mye synsing om «isens ødeleggende kraft». Her presenteres nye fotos av hva som faktisk kan skje når kalkmørtel blir offer for frost. Det dreier seg bl.a. om islinser som dannes og vokser i eksisterende svakhetsplan og sprenger biter bort. Stedet er den nye, «middelalderske» kalkovnen i Kvernsteinsparken i Hyllestad i Ytre Sogn.

This fall I joined the Wadi el-Hudi expedition to the famous Middle Kingdom amethyst gemstone mines in the Eastern Desert south-east of Aswan. The expedition is led by Dr. Kate Liszka of California State University San Bernardino (US), and over the last few seasons it has excavated and documented the ancient mining settlements in very high detail. My task was to take a closer look at the geoarchaeology – to try and understand relationships between geology and mining. It is hugely important to document what is left, for the ancient mining area is now at high risk from looting, modern gold mining and stone quarrying. Continue reading
I wish to thank my clients, partners, colleagues and followers of my website for a fine year! The very best to you all for 2016! With a cavalcade of images, I would like to recapitulate a few 2015 events. First of all, I was finally able to finish my book on the history of stone quarries, which was published jointly by The Restoration Workshop of Nidaros Cathedral and the Geological Survey of Norway. But my work took me to many parts of Norway, from a Mesolithic quartz quarry near Arendal, deep down south, to the fascinating rock art at Alta, far in the north. Though I was not able to visit Egypt last year, I’m still publishing papers on the geoarchaeology of desert quarries down there, together with good colleagues. Read on! Continue reading
I et aldeles praktfullt sensommervær var jeg siste uke Riksantikvarens utskremte på jakt etter de gamle steinbruddene som ble brukt til å bygge Edmundskirken og cistercienserklosteret på Hovedøya i Oslofjorden. Flere har gjort det samme før meg, men nå var … Continue reading
Switzerland is renowned for its castles and castle ruins, remnants of the feudal Middle Ages. A time when we may not have wanted to live! At least not as common people. But sometimes we may question whether life was much better for the nobility, for society’s elite. Take a look at the remains of Kropfenstein castle, pinned to a vertical cliff in Surselva (Grisons), hardly accessible, away from the nearest village. Great place for a special holiday, you might think – but would you have liked to reside here, year in, year out? – With photo gallery. Continue reading
Grisons – or in German Graubünden – is the largest canton in Switzerland, in the middle of the Alps, bordering Italy and Austria. It is renowned for its magnificent nature and countless medieval castle ruins. But Grisons has a truly … Continue reading
Working as a conservation scientist I care for cultural heritage. My “problem” is that I’m also interested in the history of decay, including catastrophic events; just these phenomena that turn old masonry to rubble. But I’ve never seen it “live” … Continue reading
Ten days ago winter arrived in the Swiss Alps with massive snowfall. Subsequent temperature increase and intensive rainfall led to major floods, avalanches and destruction of infrastructure such as villages and roads. Such events sometimes also affect old buildings and … Continue reading
Over the last few weeks I’ve been back in Norway for projects on conservation of medieval castle ruins, as well as on provenance of medieval and more modern building stone. Here are some impressions!*
