Due to its geographic location, the harbor between Ilovik and Sveti Petar has been used as a safe anchorage since ancient times. This also brought the first inhabitants to these islands. The oldest traces of civilization are from the
Ilirian tribe
Liburni. Visitors can also see evidence of the presence of the civilization of
Ancient Rome on the island. The remains of Roman buildings, mosaics, coins, a burial sarcophagus as well as an underwater archaeological site have been located in this area. One notable feature of Ilovik's culture is the burial rites. After church services are held on the main island of Ilovik in the church of Saints Peter and Paul (), the body is taken by boat to the cemetery, which is located across the water on another small island named Sveti Petar. The walls enclosing the present-day cemetery date back to the 11th century and were part of a
Benedictine monastery. Sveti Petar also houses a summer monastery for monks of the
Franciscan Order and the remnants of a small castle, which was built in 1600 by the
Republic of Venice. The castle was erected by Filippo Pasqualigo to defend the area from pirates (). The first
Croats arrived on Ilovik at the end of the 18th century from
Veli Losinj. This marked the beginning of the modern-day Ilovik. The oldest recorded name of this island, (translated from
Latin: "Island with No Name"), is from AD 1071. In the 13th century, it is mentioned as (translated from Latin: "Saint Peter of the Cloud") and later (translated from Italian: "Saint Peter of the Cloud"). The Croatian inhabitants named the smaller island Sveti Petar (Saint Peter), more known as 'Priko' the larger Tovarnjak ("Donkey" in English), and finally Ilovik i Sveti Petar. Locals call it San Piero. From 1920 to 1947, Ilovik and Sveti Petar were part of the Kingdom of Italy following the Treaty of Rapallo, which assigned the Cres and Lošinj archipelago to Italy. Administratively, it belonged to the Province of Pola, within the District of Lussinpiccolo, as part of the municipality of Lussingrande. The islands remained under Italian rule until the 1947 Paris Peace Treaty, when they were ceded to Yugoslavia, later becoming part of modern Croatia. ==Population==
