'''Ertholmene''' (formerly spelled ''Ærtholmene)'' is a small archipelago in [[Denmark]]. The largest island is '''Christiansø''', whose name [[Pars pro toto|is often used with reference to the entire archipelago]].<ref name=":0">{{Cite web|url=http://denstoredanske.dk/Danmarks_geografi_og_historie/Danmarks_geografi/Bornholm/Ertholmene|title=Ertholmene|last=Jørgensen|first=Jens Riis|date=7 December 2016|website=Den Store Danske|publisher=[[Gyldendal]]|access-date=24 April 2020}}</ref> Ertholmene are situated {{convert|18|km|mi}} northeast of [[Gudhjem]], [[Bornholm]], and include Denmark's [[Extreme points of Denmark|easternmost point]].<ref name=":0" /> Two of the islands, Christiansø and Frederiksø, are inhabited,<ref name=":0" /> with a combined permanent population ({{As of|2024||lc=y}}) of 91.<ref>{{Cite web|url=https://www.statistikbanken.dk/statbank5a/SelectVarVal/Define.asp?Maintable=BEF4&PLanguage=1|title=Population 1.

Historically an important navy location, the fortress closed in 1855. Since then there has been no operable military infrastructure on the archipelago, but it remains under the formal administration of the [[Minister of Defence (Denmark)|Ministry of Defence]], which employs 25 to 30 people for maintaining the islands' civilian infrastructure, museum and historical buildings.<ref name="FM2023">{{cite web| title=Christiansø Administration | url=https://www.fmn.dk/da/ministeriet/forsvarsministeriet/christianso/ | publisher=fmn.dk | access-date=8 March 2023 }}</ref> Today the economy of Ertholmene is almost entirely based on [[tourism]], with tens of thousands of visitors each year, the majority on day-trips from Bornholm during the summer months.<ref name="FM2023"/> The archipelago's buildings and nature are protected by law, and access to the uninhabited islands is restricted.<ref name="RI1984">{{cite web| title=Bekendtgørelse om fredning af øgruppen Ertholmene og omliggende søterritorium | url=https://www.retsinformation.dk/eli/lta/1984/576 | date=20 November 1984 | publisher=retsinformation.dk | access-date=8 March 2023 }}</ref>
