Caesar referred to the fort of the Eburones as Aduatuca, and this has led to a widely accepted proposal that this can be equated to Tongeren. There are counter arguments that the word ""Aduatuca"" was probably a general word for a fort in this region, meaning that there might have been more places with the same name, and that Tongeren shows no signs of pre-Roman occupation, nor the hilly terrain described by Caesar. There was also a distinct tribe in the area known as the Aduatuci. On the other hand, it has the same name and function as a local capital, and is in generally the right area. If it is not Tongeren itself, the Aduatuca of the Eburones might be the ancient fortification of Caestert in nearby Riemst.
