Katwijk aan Zee (literally, Katwijk-on-Sea) is a seaside resort located on the North Sea at the mouth of the Oude Rijn. It is situated in the municipality of Katwijk and the province of South Holland.
The name "Katwijk" probably has its origins in the name of a Germanic tribe called the Chatten (Chatti). The Dutch word "wijk" means "area", so the name probably meant something like "the Chatti area".
In Roman times, Katwijk was a place of strategic importance. It was located at the Roman Empire's northern border, at the mouth of the Rhine river, which in Roman times was larger in this area than it is today. There was a good deal of traffic along the Rhine. Katwijk was also a jumping-off point for the voyage to Britain. Built during the reign of Emperor Claudius (41–54), the town's name was Lugdunum. The town's name was later associated with the name of the city of Leiden, but this is now thought to be incorrect.
After the Romans left the settlement was abandoned and the area largely depopulated, except for small, isolated groups of Frisians ekeing out a living along the changing coast. The area was Christianised by British and Irish missionaries around the 9th century.
Katwijk ( pronunciation ) is a coastal municipality and town in the province of South Holland, which is situated in the mid-western part of the Netherlands.
