Very close to the FK Metalac stadium is located city stadium where plays more famous club FK Sloga Kraljevo. Gradski stadion (city stadium) is located in the industrial street. In its vicinity there are bus and railway stations. Stadium owns two stands, north and south. Interestingly, the north and south stands are located along the length of pitch which is rarity, compared to most stadiums in the country where the north and south stands are located behind the goals. Stadium's capacity is around 5.000 spectators. Although the first club in Kraljevo was established in 1919, Sloga was founded in 1947. Sloga in just finished season was a champion in his third league, so it will again play in the second rank of the competition, which is called Prva liga Srbija. Unfortunately, the gates were not open when I was there, and I could not get to the pitch, so I found an alternative method that I made a few photos.
Unofficial site of the club can be found here.
