Castricum aan Zee is the seaside resort of Castricum. It is located on the North Sea coast at {{coord|52.5563|4.6077|display=inline}}. It used to be called Bakkum aan Zee, and mainly consists of holiday homes, camping sites and the occasional house. Duincamping Bakkum is the oldest camp site of the Netherlands. The dune area used to be owned by [[Sophie, Princess of Albania]]. In 1906, a group of nature lovers asked permission to camp. The princess granted permission, and it developed into a permanent camp site.<ref>{{cite web|url=https://www.plaatsengids.nl/bakkum-aan-zee |title=Bakkum aan Zee |website=Plaatsengids |access-date=27 April 2022 |language=nl}}</ref>

In 1942, construction started of the [[Atlantic Wall]] to defend against an Allied invasion. As part of the wall Stützpunkt Castricum was built, and 104 bunkers were constructed in the dunes. Many have been demolished, but some are still hidden under the sand. In 2020, a previously unknown bunker was discovered buried in the sand.<ref>{{cite web|url=https://www.castricummer.nl/onbekende-bunker-uit-de-tweede-wereldoorlog-ontdekt/ |title=Onbekende bunker uit de Tweede Wereldoorlog ontdekt |website=Castricummer |access-date=27 April 2022 |language=nl}}</ref>
