With 800 ha, the Osterwald is the largest contiguous forest area on the Zingst peninsula. In this forest area, which is located between the village of Zingst and the Sundische Wiesen, six primeval redwood trees were planted in the 1955s. A younger seventh tree was planted later and completed row. These trees are considered living fossils among conifers and were originally planted in the Osterwald for research purposes. In the meantime, the trees have reached a stately height and are an attraction in the Osterwald.
