Transylvania's main city, Cluj-Napoca, is seen as the region's informal capital. But Transylvania was also ruled from Alba Iulia during its dependence from the Ottoman Empire, and the seat of the Transylvanian Diet was moved to Sibiu for some time in the 19th century.

In popular culture, Transylvania is mainly known as the seat (and origin) of Count Dracula. This vampire story by Bram Stoker is based on a local nobleman Vlad III the Impaler, known for his cruelty. It also was the home of Elizabeth Báthory.
