The article contains a detailed characteristic of tin sarcophagi of Catherine Ursula from 1634, Anne Croy from 1663 and Ernest Boguslav Croy from 1684 found in St Jack’s Church at Słupsk. Between 1978 and 1983 these objects were subjected to conservation in Monuments Conservation Workshops (PKZ) — Warsaw Section. The author has discussed the condition of sarcophagi, their technological and working characteristics as well as studies on the formulation of tin alloy used to make them. During conservation work on sarcophagi workshop punches have been uncovered that suggest Gdansk’s workshop of the Gieselers as the place of the execution of sarcophagi. A programme of conservation work realized in preserving sarcophagi has been discussed as well. The article is part of a monographic work on „Conservation of Tin on the Example of Tin Sarcophagi” , carried out in the Institute of Monuments History and Conservation attached to N. Copernicus’ University at Toruń.
