Codlea (Romanian pronunciation: [ˈkodle̯a]; German: Zeiden; Transylvanian Saxon dialect: Zäöeden; Hungarian: Feketehalom) is a city in Brașov County, Transylvania, Romania.

In Romanian, măgură means "large hill, mound, forest located on a high place".

The German name's origin is unknown, but there is a theory that it was derived from Zeidler,[citation needed] an antiquated word for "beekeeper".

[3] During the 13th century, the Teutonic Order built a fortress known as Schwarzburg ("black castle") near the "Măgura Codlei".

The castle's name was first noted in 1265 and was rebuilt for the last time in 1432 by the craftsmen's guild that worked in the town.
