Puijontie, Kuopio, Finland
The description on this postcard (in Finnish) says that it is a reprint of a 1920 photo by Lauri Marjanen of Puijontie (“street of Puijo”) in Kuopio, Finland. Today, Puijo Hill is a major tourist attraction. In addition to one of Finland’s first nature preserves, an area of about two square kilometers (which doesn’t sound like much, but that works out to nearly 500 acres), Puijo is home to a winter sports center and frequently hosts Nordic Ski Jumping World Cup events.
At the peak of the 150-meter (~500 foot) hill is a 75-meter tall observation tower, complete with souvenir shop and rotating restaurant. Jenni, who sent this card along from Kuopio, says that, in 1920, there was a 24-meter observation tower at the top of the hill, presumably not as fancy. The old tower was demolished in 1963 to make way for the new one.
Tampere, Finland has a similar observation tower, called Näsinneula (see a postcard of Näsinneula here); they borrowed the idea of a rotating restaurant from Puijo Hill.
