Episcopal Complex of the Euphrasian Basilica in the Historic Centre of Poreč

The Episcopal Complex of the Euphrasian Basilica in Poreč is a late Roman and early Byzantine church complex on the Istrian coast of Croatia, notable for a well-preserved 6th-century basilica and its mosaics. The complex is the focal point of Poreč’s historic centre and illustrates ecclesiastical architecture from Late Antiquity onward.

The basilica’s interior displays a richly decorated mosaic programme with gilded tesserae and figural compositions dating to the 6th century; adjacent elements include the baptistery, episcopal palace and a bell tower added in later periods. The complex occupies a compact archaeological and architectural block within the medieval town and is a central attraction for visitors interested in early Christian art.

The basilica was constructed in the 6th century during the episcopate of Euphrasius and formed the centre of the city’s Christian community. Over subsequent centuries the complex was adapted and extended, with medieval and later additions integrated into the original Late Antique plan.

The complex stands in the old town of Poreč on the western coast of the Istrian peninsula, overlooking the Adriatic and forming the historic heart of the modern town.

• 6th-century mosaics: The basilica's mosaics date to the 6th century and feature extensive use of gold tesserae and symbolic Christian imagery, preserved within the extant apse and nave areas.
• Continuous use: The episcopal complex demonstrates continuity of Christian worship on the site from Late Antiquity through the medieval period and is a core element of Poreč's historic centre.
