Dolmens near Knockane

Augustus 2008, declination correction -7° included, measuring phase III

According to Borlase [51] a third dolmen should have existed on the same field as those two dolmens. Unfortunately the field was covered with blackberries, so that the remains could not be found. Thanks to mister Denis Czeedon from Knockane, who kept open a small path to the field for years on voluntary basis, both existing dolmens can be visited still.

Both dolmens stand beside one another at a distance of approximately 10 meters. Only the orientation lines are measured - no sizes are taken. The mutual dimensions are deduced from the intersections of the orientation lines and the comparison to the field plan in the Survey [50]. There both dolmens are drawn on one map. On the basis of this plan and since the blue dotted lines (figure below) have the same orientation, it’s assumed, that they are a continuation of each other. With the 117° orientation line (red dotted) a mistake was made during measuring. In the records it said 140° as with the real 140° orientation line. Since with the hunebedden with satelites the 117° and 140° orientation lines form a pair, this mistake must have been a slip of the mind.
