The Dacian towns are also called davae (singular dava) since many names were composed of an initial lexical element affixed to -dava, -daua, -deva, -deba, -daba, or -dova, which meant "city", "town" or "fortress"" in the Dacian language (<PIE*dhe-, "to set, place"[4] or *dhewa, "settlement"[5]). Generally, the name indicated a tribal center or an important settlement, usually fortified.
The known towns names have been are attested by Ptolemy (1st century AD) and other ancient writers, but many have not been identified in the field yet. Conversely, there are many recent discoveries of Dacian settlements and fortresses, but most of them have no assigned names yet.
Some of the Dacian settlements and the fortresses employed the traditional Murus Dacicus (Dacian Wall) construction technique.
