The Perishable Past - On the Advantage and Disadvantage of Archaeology for Life

The aim of the article is to make clear whether and in that case why archaeology is important. Often this is seen as a self-evident fact which needs no motivation. My point of departure is a concrete example, namely, the medieval church of Mårup in Denmark which will soon fall into the sea: Why is it so crucial to save or document this church and many other traces of the past? Isn't the so-called cultural heritage condemned to destruction and oblivion? Rhetorical catchwords, cultural values, justifications and explanations within cultural heritage management, archaeology, history and social anthropology are presented and critically discussed together with indirect motivations borrowed from the literature about the abuse of the past.
