Tampere Circuit was a motorsport race track located in Tampere, Finland. The route was used for an annual motorcycle race called Pyynikinajo in 1932-1939 and 1946-1971. In 1962 and 1963, the circuit hosted the Finnish motorcycle Grand Prix, a round of the Grand Prix motorcycle racing world championship. The track ran on public streets near the Pyynikki observation tower. The event was banned after 1971 due to general safety concerns. Källa: Wikipedia.
