Firstly that the surrounding woods needed to be cleared for a better defence of the town, so Ogulin received its name because of the resulting bare area ("ogolio" in Croatian) around it.

There were a lot of lime-trees along the road from Ogulin towards Oštarije, and the people used to peel the bark, in order to get bass[clarification needed].

Ogulin is known for the legend of Đula (also Zuleika or Zula) who threw herself into the abyss of the River Dobra because of an unhappy love affair.

[6] Until 1918, Ogulin was part of the Austrian monarchy (Kingdom of Croatia-Slavonia, Modruš-Rijeka County, after the compromise of 1867), in the Croatian Military Frontier.

This is a kind of transitional micro-region neighbouring the larger regions of Croatia - Gorski Kotar, Lika, Kordun and Gornje Pokuplje.

This comprises a completed geographical whole border on the western side by the mountain massif of Velika Kapela dominated by Klek (1181 m).

This is the fifth largest karst valley in Croatia (60 km2 (23 sq mi)), and it lies 320 metres (1,050 feet) above sea level.

Approximately three kilometers south of the town centre is an artificial lake Sabljaci, formed with the purpose of accumulating water from the Zagorska Mrežnica river, and for the sake of generating electricity in the Hydroelectric power plant Gojak.

Consecrated on June 1, 179, it reflects the spirit of the time with its pleasing external appearance and the richness of various sculptural decorations.

The town of Ogulin celebrates September 14 as the fest day of its patron Saint of Extolling of the Cross.

Bernardin Frankopan, the son of Stjepan, and the founder of the town of Ogulin, erected a chapel in 16th century both for nobleman and ordinary people within the castle.

The founder of the town was Bernardin Frankopan, one of the mightiest people of his time, and the feudal master of Modruš, Plaški, Vitunj, Tounj, Zvečaj, Bosiljevo, Novigrad and Dubovac.

The County Museum of Ogulin was opened in July 1967 in several of the Frankopan Castle halls that were being renovated and prepared between 1960 and 1967.
