Kasaba Džisr -i-Kebir (Veliki Most) na rijeci Uni, kako se prvobitno nazivao današnji Kulen-Vakuf, osnovana je podizanjem džamije sultana Ahmeda I (1603-1617). Poslije Karlovačkog mira naređeno je bosanskom valiji Halil-paši da ga proširi i utvrdi. Nešto kasnije, 1713. godine, naređeno je bosanskom veziru Ahmed – paši da organizuje prijevoz deset topova i potrebnog broja đuladi i baruta iz beogradske džebhane, vojnog skladipta oružja i municije u novosagrađenu tvrđavu Džisr – i – Kebir.
Grad je nastao na umjetno stvorenom otoku uz lijevu obalu rijeke Une, tako da je uz same gradske bedeme tekla Una i n jezin umjetno prokopani rukavac. Na taj način ovaj grad, pored čvrstih bedema, imao je i vodeni obrambeni pojas. Na gradskim bedemima bila su četvera vrata i dvije tabije. Na istočnoj strani bedema bila je Horića tabija, a na zapadnoj strani Ćemalovića tabija. Jedna od glavnih gradskih vrata bila su na velikom mostu, a druga pored gradske džamije. Ostala dvoja sporedna vrata bila su na istočnoj i zapadnoj strani grada, u neposrednoj blizini tabija.
Ovaj grad se još tridesetih godina XVIII stoljeća neslužbeno nazivao palanka Mahmut – paše Kulenovića, koji je u njemu sagradio džamiju i za njezino održavanje ostavio je vakuf, po kojem se ovo mjesto počelo zvati Vakuf, a od 1836. godine Kulen – Vakuf. Gradskom vojnom posadom zapovijedao je aga kao ćehaja, pomoćnik ostrovičkog kapetana.
