Ribe (ˈʁiːpə) is a town in south-west Jutland, Denmark, with a population of 8,365 (2023). It is the seat of the Diocese of Ribe covering southwestern Jutland. Until 1 January 2007, Ribe was the seat of both a surrounding municipality and county. It is now part of the enlarged Esbjerg Municipality in the Region of Southern Denmark. It has been called the oldest town in Denmark.
The town was a center of commercial activity in the early 8th century, and this may have originated with royal influence. Coins may have been struck there in 720. Whichever king was involved in the digging of the Kanhave Canal may have been involved in the establishment of Ribe also. Trade contacts were mostly with Frisia and England. Of the over 300 sceatas found in Denmark, 216 come from in or around Ribe, most of them the Wodan type, and these were likely minted in Ribe in the early eighth century. The Ancient Diocese of Ribe was established in 948 with the consecration of Leofdag of Ribe as its first bishop.
Early in the ninth century a 2-meter wide ditch (a demarcation rather than a fortification) was dug around the town, enclosing a 12-hectare area. Later that century the ditch was replaced by a moat, 6 to 7 meters wide. Archeological evidence shows Ribe was "an active and impressive market place" in the eighth and ninth centuries, and again at the end of the eleventh century, but there is little evidence from the period in between; the town may have dwindled or even disappeared.
When archbishop Ansgar set out to christianize Scandinavia, he requested (in about 860) of King Horik II of Denmark that the first Scandinavian church be built in Ribe, which at the time was one of the most important trade cities in Scandinavia. However, the presence in Ribe of a bishop, and thus a cathedral, can only be confirmed from the year 948. Recent archaeological excavations in Ribe, however, have led to the discovery of between 2,000 and 3,000 Christian graves. They have been dated to the ninth century, indicating that a large Christian community was already living peacefully together with the Vikings at the time.
