A good example of two dolmens in a rectangular enclosure is that at Valdbygaards, near Soröe, in Zeeland. Here the enclosure is about 70 feet in one direction by 20 feet in the other--outside measurement. In this instance, the enclosing stones are smaller in proportion to the dolmens than is usually the case. On the same plate, Madsen represents a single dolmen in a much squarer enclosure.[362] It, like that at Halskov (woodcut No. 107), is represented as standing on a knoll, but whether dolmens stand so or on the flat, like that at Valdbygaards, it is quite certain they never were enclosed in tumuli, but always stood free, as they now do. [Illustration: 111. Double Dolmen at Valdbygaards. From Madsen.] [Illustration: 112. Plan of Double Dolmen at Valdbygaards.] [Illustration: 113. Triple Dolmen, Höbisch. From Keysler.] For three dolmens in one square enclosure we are obliged to go back to old Keysler, though, in this case, the engraving is so good that there can be very little doubt of its correctness.[363] It is situated near Höbisch, in Mark Brandenburg, consists of an outer enclosure of forty-four stones, and is 118 paces in circuit, and in the middle are twelve stones, of which six bear three large stones, placed transversely upon them. It is very much to be regretted that no better illustration of this curious monument exists, as it probably very closely resembles those in Drenthe, with which, indeed, he compares it; and as these form one of the most remarkable groups of this class of monuments on the continent, it would be most desirable to trace their connection with others farther east. A similar monument to that at Höbisch is figured by Sjöborg (vol. i. pl. 6), but without the enclosure; and a third, Oroust, in Böhuslan (pl. 3); but in this instance the three long stones are surrounded by a circular enclosure with two sentinel stones outside; and there are several others which show similar peculiarities in a greater or less degree.
