Herøya
Herøya is a peninsula in Porsgrunn Municipality in Telemark county, Norway. It is located between the fjords of Frierfjord to the west and Gunnekleivfjord to the east, at the mouth of Porsgrunn River. The name stems from the Old Norse word "her-eyjar" meaning an island (øya) with a horde or army (her), thus "the crowded island".
