Nijmegen is considered to be the oldest city in the Netherlands and celebrated its 2000th year of existence in 2005.
The first mention of Nijmegen in history is in the 1st century BC, when the Romans built a military camp on the place where Nijmegen was to appear; the location had great strategic value because of the surrounding hills, which gave (and continue to give) a good view over the Waal and Rhine valley.
In 98 Nijmegen was the first of two settlements in what is now the Kingdom of the Netherlands to receive Roman city rights.
In 103 the X Gemina was restationed to Vienna, which may have been a major blow to the economy of the village around the camp.
In 104 Emperor Trajan renamed the town, which now became known as Ulpia Noviomagus Batavorum, Noviomagus for short (the origin of the current name Nijmegen).
In the 4th century, Roman power decreased and Nijmegen became part of the Frankish kingdom.
