Bartoszyce

Promotion to the Third Tier came on the back of winning Group 2 of the Pomorski regional section of the Second Tier in the 2025/2026 season.

The club exists because handball in Bartoszyce had gone quiet: the sport had a home at MBKS Victoria Bartoszyce from 1952 until that section folded in 2002. The Bartoszyce Association of Handball Lovers, registered in September 2019, is not a revival of Victoria's old section but a separate body, and it took until the 2021/2022 season to actually get a team onto the court in league competition.

Matches are played at the Hala Widowiskowo-Sportowa run by the local sports and recreation centre, BOSiR, on Słowackiego street, a hall that holds 297 people. Against UKS Jedynka KODO Morąg, the fixture gets billed locally as a Derby of Warmia and Masuria.

Beyond the senior men's side, the club has fielded a masters team in the +45 category, which finished sixth at the Polish Masters Championships in 2023.

BSMS Bartoszyce has one league title and a hall that seats 297.
