Senj and the Diocese of Senj have a long and rich history dating back to ancient times. It is believed that the Senj Cathedral was built on the foundations of an early Christian basilica and is different and special in its construction. The most fruitful period is certainly the Frankapan and Korvin periods, the pre-Turkish and pre-Uskok period when there were scriptories in Senj in which books were copied, as well as a bookbinding workshop. Although the town of Senj itself resisted Turkish conquests after the defeat of the Croatian army on Krbavsko polje in 1493, many churches were destroyed. The Senj printing house was founded in Senj at that time, after Blaž Baromić printed his Breviary in Venice in 1493, and returned to Senj. We know that two Glagolitic incunabula, the Senjski Misal, Spovid općena and five other books were published by the Senj printing house. The Senj printing house is a shining example of Croatian cultural history, but also of European and world printing history. Senj was destroyed in the Second World War when the cathedral was bombed, and the Homeland War did not circumvent Senj. Today, the sacral heritage of Senj preserves the cultural heritage of the history of the city, the diocese, but also two incunabula that are monuments of world literacy, Geographie Strabonis and Josephus de Antiquitatibus ac de Bello Judaico. The Senj printing house has its significant place in the culture of printing in general.
