Until 1982 G1 (the 'G' stands for Groningen) was the only hunebed in the province of Groningen. In that year a small hunebed was found deep under the clay near Delfzijl, 25 kilometers to the north. G2 has been restored and can be admired in a museum in Delfzijl.
G1 is an incomplete hunebed. Only 2 capstones are left and there must have been 5. As you can see on the picture one of them is very impressive indeed. Too big for the stone robbers...!
