Description |
Bruddet ligger nede ved sjøkanten og rester etter kaianlegg finnes fortsatt. Det ble produsert nokså stor blokk herfra som for det meste gikk til kaianlegg i Stavanger. Bruddet ble nedlagt før siste krig, og øya er idag friluftsområde. |
Location |
Bruddet ligger på Forøya som ligger mellom Halsnøy og Randøy. Adkomst til øya bare via båt. |
