Katwijk is located on the North Sea, northwest of Leiden and 16 km north of The Hague. The municipality is essentially the area between Leiden and the North Sea. Katwijk lies along the Oude Rijn, which ends at the North Sea in Katwijk aan Zee. It shares its borders with the municipalities of Noordwijk, Teylingen, Oegstgeest, Leiden, and Wassenaar. Katwijk is by far the largest town in the Duin- en Bollenstreek ("Dune and Bulb Region"). The municipality covers an area of 31.06 km² (11.99 mile²), of which 6.41 km² (2.47 mile²) is water.
The town consists of a number of districts, including namesakes Katwijk aan den Rijn and Katwijk aan Zee. On 1 January 2005 the various districts had the following populations:
Lying on the coast, Katwijk aan Zee is (and has always been) the larger town. Katwijk aan den Rijn lies just slightly inland. Rijnsburg is east of Katwijk aan den Rijn and to the south is Valkenburg. Katwijk-Noord is north of Katwijk aan Zee.
Although consisting of historically separate towns (except Katwijk-Noord) that still today maintain separate identities, the towns have more or less grown together and merged into a single conurbation. The creation of the municipality of Katwijk is a recognition of that fact. The town hall of the current municipality of Katwijk is located in Katwijk aan den Rijn, near the boundary of Katwijk aan Zee. All these districts lie along the Oude Rijn.
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 Romans 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 Batavorum. The town's name was later associated with the name of the city of Leiden, but this is now thought to be incorrect.
In 1231, the first reference to Catwijck appeared in records.
The history of the modern municipality of Katwijk is essentially the history of its constituent parts, which for each village extends back to Roman times. However, Katwijk aan Zee, Katwijk aan den Rijn and Valkenburg were part of the same heerlijkheid called "Beide de Katwijken en 't Zand" (or something similar). They have been administratively joined for centuries despite their differing characters. Katwijk aan Zee was a fishing town and Katwijk aan den Rijn had an agricultural character.
During World War II, Katwijk aan Zee was heavily damaged. On May 1, 1942, beach access was no longer permitted and large scale evacuation took place. From October 1943 houses were demolished in relation to the construction of the Atlantic Wall.

Tourist attractions 
Katwijk is a seaside resort with a wide sandy beach. Its attractiveness is mainly due to its laid-back atmosphere. The boulevard along the shore is not spoiled by large hotels or apartment blocks and has not given in to an excessive commercialisation. Although most buildings lining the boulevard are tourist apartments and pensions, most are just three floors high (and none more than 5) and offer a distinctive 'feel' of the 1950s. Besides the beach, there are a few museums in Katwijk, like the old fisherman's museum Katwijks Museum and the Spinoza-museum. A few kilometers inland there is a narrow gauge museum where a museum steam locomotive ride can be taken around Lake Valkenburg. Katwijk has many hotels and three camping places, mostly situated in the dunes.
