Rtina is situated, as the Croatian meaning of the name confirms, on a big cape about 43m high above sea level. That cape represents the most northern part of the Dalmatian coast that is connected to island Pag by a bridge. It is located about 5km north-west from Ražanac. Written documents originate from the time of a well known poet Juraj Baraković, who mentioned that his grandfather received three villages: Plemiće, Brus i Oštri Rat (Rtina). From 1890 till 1921 Rtina was named Hrtina. Close to the Pag Bridge are the remains of a Medieval Templar Fort – Fortica.
By the last National census (2001) Rtina has 473 inhabitants. The area is 17,98 km2 big, and population density is 26 people/km2. Today Rtina has a church of St. Simon Bogoprimac, built in 19th century, but fully destroyed in 1962 during the time of Yugoslavenian communist regime. The church was rebuilt and dedicated on June 24th, 1990. At that time the priest was Ante Erstić. A new cemetery was built next to the church. The church belongs under the Parish of Ražanac.
The hamlets belonging to to Rtina are: Miletići, Benići, Vrankovići, Stošići, Miočići and Škaulji. Rtina has an Elementary school, a branch of Elementary school of Juraj Baraković in Ražanac. Rtina sees its future in tourism, making better tourist results every year. It is also well known by Rtina international swimming marathon.
