Being one of the historical works of Trabzon, Trabzonspor Museum is on the second floor of Sadri Şener Social Facility Building. The museum which displays many championship cups reveals that the Trabzonspor Sport Club has an important place in the Turkish football history. The most interesting cup in the museum is the ‘half cup’ which was shared with Ankara Havagücü Sport Club in the 1958 Turkish Amateur Football Championship.

In the final match of Turkish Championship which was organized by the Football Federation in 1958, Trabzon İdmanocağı and Ankara Havagücü sport clubs had the same points and averages, and both refused to hold a new match. Hence the Football Federation declared both of the clubs as the champion and the cup was divided into two.
