Gradska sportska dvorana Ivica Glavan – Ićo

The Gradska sportska dvorana Ivica Glavan – Ićo does not shout for attention. The hall was named after Ivica Glavan "Ićo," a former mayor who championed the project and laid the foundation stone in 2013. It opened on October 22, 2018, a date chosen because it coincides with the birthday of the late Croatian basketball legend Dražen Petrović.

The interior features modular parquet of the highest FIBA level, installed to meet professional standards. The official seating capacity is 298 seats, though it is often rounded to 300. This figure is below the 800-seat requirement for the top-tier Croatian HT Premijer Liga. Consequently, home teams like KK Alkar sometimes play in neighbouring towns or use conditional permits. The highest recorded attendance was 1,000 spectators during a Basketball International League (NBL) match between KK Alkar and Bristol Flyers. Other notable attendances include 550 for a match against Šibenka and 450 for another.

The venue serves as the home ground for KK Alkar, ŽRK Sinj, and various youth and amateur teams for volleyball and futsal. It hosts the annual Handball Tournament in Honor of Our Lady of Sinj and the Sports-Educational Camp organized by the Univerzalna sportska škola Ivana Pavla II. The construction companies involved were "Poljud vile" and "Cetina." The city bore most of the cost after failing to secure significant co-financing from county or state bodies. There are no other venues with this exact name in Croatia. The hall is managed by the Zajednica športskih udruga grada Sinja.
