The Satrupholm Peat Bog is located in the region of Angeln in northernmost Germany, c. 20 km southeast of Flensburg. It is known to be a Late Mesolithic/Early Neolithic (late Boreal to early Subboreal period) settlement cluster in the hinterland. In prehistoric times this bog has been a large lake with an approximate expanse of 1.8 km2.

The bog evolved from three small glacial lakes with depths between 8 m and 11.5 m which merged with the beginning of the holocene.

On islands in the lake basin and on mineral peninsulars are today known more the 20 mesolithic sites that were observed by amateur archaeologists during peat cutting activities in the 1920s and 1930s.

One of these sites, Satrup LA 2 (Bondebrück), is located at the northern edge of the bog, where a rich amount of typical mesolithic (kongemose) artefacts (core axes, burins, trapezes and regular blades), were collected from the plough layer on the surface of a mineral hill. This knowlegde lead to four excavation campaigns between 1947 and 1957 by H. Schwabedissen (University of Cologne), where in peat layers more than 30 red deer antler axes were obtained. A few pieces of undecorated pottery sherds among the Late Mesolithic finds ensure that a Terminal Mesolithic (Ertebølle) occupation is present here as well.

Recent excavations at the Satrup LA 2 site.

Unfortunately the site was never published in detail, and it is in the focus of present day research (2010 and 2011) to confirm the conclusions which Schwabedissen draw in the last century, and which F. Feulner (2009) presented in his phd on the Satrup Peat bog sites when analysing the original unpublished data.

The new excavations show a gradual degradiation of the organic deposits and a rapid process of destruction of organic finds, especially animal bones and bone and antler tools. In all bones a very low amount of collagen was detected which makes them very unreliable for radiocarbon dating.

It is important to show that this unique and significant bog site is vanishing within the next years because of the lowering of the water Table due to heavily draining since the 1940s.
