The ski jump in Pokrzywna at Szyndzielowa Kopa was built by section of Mährisch-Schlesischer Sudetengebirgsverein (MSSGV) from Prudnik in 1931. Originators of building it were Konrad Hannak from Prudnik and local club "Klub Narciarski i Tenisowy". This ski jump was built to popularize ski jumping in Opawskie Mountains. Inaugural competition was watched by thousands of people.
At Seiffentalschanze special terraces for spectators were built. Take-off was horizontal and made from stone. Longest jumps there was about 40 metres.
Seiffentalschanze was used to late 1940's. Last competition there was organised in 1947. Ski jump wasn't used later because snowfalls there wasn't frequent and it was hard to prepare it for jumping.
In 2007 it was planned to built new ski jump with plastic matting in place of old Seiffentalschanze and small ski jump for kids and youth athletes next to it, but costs were too high and project wasn't realized.
