Time Out says
For more than 300 years, a jousting tournament has taken place in Sinj, small town in inland Dalmatia, half an hour from Split. Commemorating a historical battle against the Ottoman Empire, it’s a popular event in which competitors in historic costumes ride around trying to hit target rings. An important part of the tradition is that only people from Sinj and vicinity can participate, like Siena’s Palio. Make sure you book tickets in advance, especially for the main competition on Sunday. Even if jousting isn’t your thing, the streets of Sinj will be filled with people and it’s a fun day out.
