Alba Iulia is located in the centre of Romania, south-east of the Apuseni Mountains, and is one of Romania's most important historical cities. Alba Iulia was the capital of Dacia Apulensis (1st century), and of the Transylvanian Principality (16th century). The first step towards the temporary unification of the Romanian principalities was made here (Michael the Brave, November 1st 1599). We have to mention the medieval cultural tradition, when the Orthodox Archbishopric was established here and Alba Iulia was an important centre of Romanian printing houses. The New Testament (1648) and The Psaltery (1651) were first printed here.
