Senj is an old settlement which was founded on the hill Kuk, east of the town more than 3000 years ago.In the middle of the 15th century the millitary forces of the Hungarian-Croatian king Matija Korvin came to town.In the 1469. Senj became a center of its captaincy, established because of danger which was coming closer and closer from the Turks but also with the aim to defend from the policy of Venice. The Ottoman campaigns to this area were especially during the firs half of the 16th century. At that time the neighbouring places were totally devasteded and the town became the refuge for a large number of refuges from the occupied areas.
The millitary units were formed of the refuges. They were the famous Uskoks who successfully defended Senj till the twenties of the 17th century and who managed to cause hard lossesto the armed forces of the Ottoman Empire and Venice.
The days Of Uskok is a mediaeval festivity and during these two days visitors can take part in lots of mediaeval attractions, f.e.: a mediaeval market with ancient crafts, traders, coinsmiths, entertainers, musical performances, knights' tournaments and so on.
