A re-assessment of the hunehedden O1, D30 and D40: structures and finds
Re-investigations at three hunebedden excavated by A.E. van Giffen in 1918 are described and changes to the original conclusions given. O1 is shown to have had a minimum of seven pairs of side stones. The mounds of D40 and D30 are shown to have been constructed in several phases; the primary mounds did not completely cover the chambers. The finds have been re-analysed.
