Near Stavenhagen in the Mecklenburg Lake District in Mecklenburg-Western Pomerania, you can marvel at something very special in a park: the thousand-year-old oaks. The trees, also called Ivenack oaks, are said to be between 800 and 1,300 years old, making them among the oldest in Europe. The old oaks have an impressive trunk circumference of seven to nine metres, the oldest oak even up to eleven metres. This makes the mightiest tree the largest living creature in Germany as well as the largest English oak in the world. During examinations in 1996, it turned out that the thousand-year-old oaks are amazingly healthy and the trunks are completely undamaged.
