Abstract [en]

Sweden has had a long lasting connection with the Ottoman Empire. From the Viking age to the 18th century warfare and cooperation has been ongoing. Even the Silk Road was a time extended to the Baltic. That means 1000 years of cultural contacts. After the battle at Mohacs in Hungary 1687, Swedish soldiers and officers looted the Ottoman war baggage. A great number of objects, today artefacts, were transported to Sweden. Among them, in the collection of Skokloster Castle, we will today find tents with carpets, used by high ranking Ottoman officers as well as high-tech composite bows used by cavalry soldiers. This paper discusses why the mentioned textiles and wooden objects, made for use in the Mediterranean climate, has survived so well for more than 300 years in the Baltic climate far north in Europe.

Skokloster Castle is a heavy stone and brick building without any climatisation. The castle has only open fireplaces and ovens and they have not been used for the last 300 years. There is no electric lighting installed why visitors have to admire the 17th century interior design and the large paintings collection in daylight, summertime only. We have here a very good example of preventive conservation by passive means. The main philosophy of the conservators and curators working at Skokloster Castle with the large collection (50 000 items) is to “let it rest in peace”. The indoor climate at Skokloster castle has been under observation for generations. The castle and its collections were turned into an entailed estate already in 1701 by the owner Margareta Juliana Wrangel, the oldest daughter and heir of the founder of Skokloster castle. This was for tax reasons but also to preserve the memory of her great father, the fieldmarchal. That means that by law the proprietors had to write detailed inventories for every generation of owners. Thus today´s conservators and curators have a detailed history of the preservation climate and the conditions of every object in the collection. The indoor climate follows the outdoor over the season. Stormy weather increases the air infiltration and disturbs the stable indoor climate. Subsequently warm summers may create high relative humidity which is a risk for growing mould. Never- theless the mayor part of the collection is in good condition. Today we have year long observations of temperature, relative humidity and air change rate in the castle, which will be presented and discussed in the paper.

This paper intends to invite to a discussion of best preventive climate and conservation actions having the coming climate change in mind.
