FOREWORD
Composing an inventory of oblong and key-hole
shaped grave enclosures is a project going back
to the Bronze Age Campaign of the Council of
Europe from f994-1996 (Pautreau et al. 1998).
In 1995, J.-P. Pautreau and O. M. Wilbertz decid-
ed to undertake such an inventory and mapping
project for certain types of enclosures. They con-
vinced further colleagues to collaborate, result-
ing in the following study areas: Belgium (J. Bour-
geois, K. Verlaeckt, G. De Mulder), Germany (B.
Herring, O. M. Wilbertz), France (J. Gomez de
Soto, J.-P. Pautreau) and the Netherlands (E.
Drenth, H. A. Groenendijk).
As the work had to be carried out alongside the
authors’ regular occupation, and mostly in their
spare time, it has been a rather drawn-out proc-
ess. During this time, several authors’ meetings
were held to discuss the details of the inventory.
On the one hand, ‘the main objective of this
inventory is not completeness, but to illustrate
the distribution of these enclosures in its entire
geographic extent’ (Pautreau et al. 1998). Yet on
the other hand, the depth of study desired by our
Dutch colleagues had to be taken into account5.
The result is a catalogue divided into four sec-
tions, all as standardized as possible, an essay on
the Dutch enclosures and a glossary. Initially, the
aim was to illustrate finds alongside the different
sites, but in the course of the project it became
clear that all too high expectations would have
further delayed the whole project and ultimately
endangered its very completion.
The authors were strongly supported by a number
of colleagues, listed in the various sections. In
addition, we would also like to express our grat-
itude here. Without their enduring help, this
inventory would not have been possible6.
We are also very grateful to Jörg Birnstiel, who
generated the maps, and to Vijay Diaz and Jochen
Greiner, who revised the plans, scanning large
printed copies, unifying the orientation, stand-
ardising the scales and simplifying plans and
keys. They all are employed by the Niedersäch-
sisches Landesamt für Denkmalpflege.
Furthermore we thank our editor, Dr. Henning
Haßmann, for accepting the inventory for the
series “Materialhefte zur Ur- und Frühgeschich-
te in Niedersachsen” and the publisher, Dr. Bert
Wiegel, for producing the books at very short
notice, allowing us to present the inventory in
winter 2008/2009.
