Cluj-Napoca is the capital of Romania’s Transylvania region and the second-most populous city in the country. Currently ranked the 10th most livable city in Europe, it is a major academic center, with a thriving arts and culture scene and a booming tech sector
The venues of the Convocation were the János Zsigmond Unitarian High School and the First Unitarian Church of Cluj/Kolozsvár, conveniently located next to each other in the city center.

The most famous son of the city, from a Unitarian perspective, is Francis David (Dávid Ferenc), the founder of the Hungarian Unitarian Church. Under the influence of his teachings, Prince John Sigismund (János Zsigmond) of Transylvania became a Unitarian; in 1568, at the Diet of Torda, an unprecedented decree of religious tolerance and denominational diversity was proclaimed, laying the foundations for freedom of thought, conscience, and religion.
