The story of Olympic Stadium began in 1927, when City of Helsinki and several sport associations created the Stadium Foundation. The purpose of foundation was to build an adequate venue for the summer olympics. Construction of the Olympic Stadium began in 1934 and it was completed in 1938. It was designed in functionalistic style by the architects Yrjö Lindegren and Toivo Jäntti.
The stadium was built to host the 1940 Summer Olympics, which were moved from Tokyo to Helsinki before being cancelled due to World War II. After 12 years delay the XVth Olympic Games were finally held in Helsinki Olympic Stadium in 1952. The stadium was also the venue for the first World Athletics Championships in 1983 as well as for the 2005 World Championships in Athletics. It is also the home stadium of the Finland national football team.
Olympic Stadium is still in active use. The National Sports Museum is also situated to the stadium and the 72 meters high tower is popular place to see the nice view over the downtown of Helsinki.
The Externsteine (Extern stones) is a distinctive sandstone rock formation located in the Teutoburg Forest, near the town of Horn-Bad Meinberg. The formation is a tor consisting of several tall, narrow columns of rock which rise abruptly from the surrounding wooded hills. Archaeological excavations have yielded some Upper Paleolithic stone tools dating to about 10,700 BC from 9,600 BC.
In a popular tradition going back to an idea proposed to Hermann Hamelmann in 1564, the Externsteine are identified as a sacred site of the pagan Saxons, and the location of the Irminsul (sacral pillar-like object in German paganism) idol reportedly destroyed by Charlemagne; there is however no archaeological evidence that would confirm the site's use during the relevant period.
The stones were used as the site of a hermitage in the Middle Ages, and by at least the high medieval period were the site of a Christian chapel. The Externsteine relief is a medieval depiction of the Descent from the Cross. It remains controversial whether the site was already used for Christian worship in the 8th to early 10th centuries.
The Externsteine gained prominence when Völkisch and nationalistic scholars took an interest in the late 19th and early 20th centuries. This interest peaked under the Nazi regime, when the Externsteine became a focus of nazi propaganda. Today, they remain a popular tourist destination and also continue to attract Neo-Pagans and Neo-Nazis.
