Hidden in the Sepen bay on the island of Krk, near Omišalj, lies one of the most fascinating archaeological sites on the northern Adriatic. Fulfinum was an antique Roman town founded in the 1st century AD to settle veterans of the Flavian emperors, while Mirine is an impressive early Christian complex built on its outskirts in the 5th-6th century.

This is a place where history blends with landscape - the ruins sit on flat ground surrounded by fertile fields and overlooking a well-sheltered bay that once served as a harbor. Walking among the remains of the forum, capitolium, thermal baths and the cross-shaped early Christian church gives a real sense of stepping into a long-forgotten town. In spring and autumn the surrounding meadows add a peaceful atmosphere, while summer brings a cooling sea breeze from Sepen bay. This is not a mountain peak but a historical stop worth combining with walks around the island of Krk.

How to get there

• Omišalj – local road and path to Sepen bay, about 20-30 minutes, easy route
• Alternatively from Njivice – coastal path towards Omišalj and onward to the site

Practical information

• Open-air archaeological site, accessible on foot
• The complex includes a forum, capitolium, town basilica, thermal baths and an early Christian church with cloister
• Linked to the Benedictine abbey of St. Nicholas

Fulfinum, planned as a model town of the Flavian era, was likely one of the first casualties of the collapse of antique civilization - yet its spirit lived on through the Christian complex of Mirine, built upon its ruins.
