KBM, and Zavarovalnica Sava (Zavarovalnica Maribor prior 2016). Kit manufacturers Crest The current crest of the club is based on the official coat of arms of the city of Maribor, which is in turn based on a 14th-century seal with minor differences. The badge is formed in a shape of a shield, and shows the former Piramida Castle that used to stand on top of the Pyramid Hill before it was demolished at the end of the 18th century. A violet blossom forms the backdrop. Unlike the coat of arms of the city of Maribor, the club's current badge does not represent a white dove facing down towards the castle, but a minimalist portrayal of an athlete. At the top of the shield the name of the club and the year of its foundation is inscribed. The entire badge uses only two colours, purple and yellow. Previous versions of the crest included white, one of the club's traditional colours, in the form of a white castle in the centre and a white ball that was on top of the shield. Since May 2012, the crest includes a yellow star at the top, indicating the first ten domestic titles won.

Prior World War II, the ground consisted of just a pitch with a small stand, which was destroyed during the war. The site has been used for football since at least the early 20th century; between 1910 and 1960, it was the home ground of many teams based in Maribor, including Marburger Sportvereinigung, SV Rapid Marburg, SK Hertha, SK Rote Elf, I. SSK Maribor and NK Branik Maribor. After the war, the ground was renovated and opened in 1952, but the main grandstand was not built until the early 1960s. On 25 June 1961, Maribor played its first match at the stadium, against Mladost Zabok, when the
