220 million years ago, glowing hot molten rock masses intruded into fractures in the earth's crust in the outer parts of Hordaland. Some of these are believed to have reached the surface and formed lava flows, which since have been eroded away by wind and weather. But, most of these flows solidified into diabase sills before they got to the surface.
The old hostelry centres were strategically placed with good harbours and anchoring conditions where people travelled. GODØYSUND, or Gøysundet, as it was called, was in the middle of Tysnes Parish, with easy access from the sea, also for the local population. Gøysundet is amongst the oldest hostelries in Sunnhordland.
