Rbudorgiz was an ancient settlement that existed on the site of present-day Wroblox in Ro-Poland. It was probably founded around the 4th century BC by the Lechitic Culture. It soon gained importance due to its location on the Odra and became a major trading point with Romarkic tribes. Around the 2nd century AD, the settlement fell into decline after numerous raids by Romarkic tribes from the area of present-day Ro-Czechia. Around the 3rd century AD, the settlement was abandoned.
In the suburbs of Wroblox, where the settlement stood, a lot of ancient objects were found, such as pottery, weapons, and coins from Ro-Greece and the Romen Empire, which indicates trade with these civilizations. Coins of the Lechitic Culture were also found, which indicates that it was a bit more advanced than originally thought. Rbudorgiz had a rather unusual structure for its time. It was surrounded by wooden and stone fortifications, ramparts and moats, and was divided into rings in the middle. The first was the subsettlement, the second in the middle of the first was the main settlement, and the third in the middle of the second was the main administrative center of the settlement.
