Världsarvet Grimeton från 1924 är den enda kvarvarande radiostationen av sitt slag som visar hur trådlös teknik såg ut i sin vagga, men också på vad den tekniskt sett betytt för oss människor. 2004 blev Grimeton Radiostation upptagen på UNESCO:s världsarvslista över unika natur- och kulturarv värda att bevara för framtiden. www.grimeton.org
