the architectural surfaces, which the cloister received when it
was remodelled with vaulting around 1230—1250, can be
said to have been applied on a layer offne Urne plaster. The
contemporaneous polychrome painting on the architectural
sculpture is almost completely lost. Only a small capital still
shows remains ofgrey paint, which has been applied directly
to the stone surface. In later periods the cloister was also re-
peatedly renovated, as indicated by the numerous fragmen-
tary remains.

Architecture and architectural sculpture of the
Western wing of the cloister — Art-historical and
technological aspects
The early 1 Ith Century west wall ofthe cloister had a succes-
sion of round-arched niches, which were evident in Bern-
ward’s monastery complex and in the crypt. The steppedpor-
tal to the north-west side wing, which originated in the last
third ofthe 12th Century, under Bishop Adelog, comes from
the same stonemasons who made the capitals of the long
house. A workshop using an embossed insignia fom Bam-
berg inserted two trefoil-arched portals around 1220/30.
Around 1230 and 1250 the west wing was vaulted. The
richly decorated capitals show strong technical and stylistic
similarities to the architectural sculpture in the ambulatory
of the Magdeburg cathedral, which the sculptor active in
Hildesheim would have known of or seen, but they also
indicate a knowledge of sculpture from-the Lower-Rhine
region.

Examination results of architecture and surfaces
Although the remains of post-medieval polychromy can not
be dated exactly, it can be established that the interior and
exterior of the cloister were continually maintained using
lime-based techmques. The surface ofthe vaults and walls, as
well as the hewn stone, were not only aesthetically renovated,
but also protected by the application of plaster, distemper
and a lime-based wash. It is thanks to theprotection through
this historical tradition of maintenance and repair that —
despite all the damage — so much ofthe medieval structures
can be seen today.

Conrad Wilhelm Hase and conservation-restoration
of the wing of St. Michael in the third quarter of the
19th Century
The Western wing ofthe cloister was restored by the architect
and restorer Conrad Wilhelm Hase in the third quarter of
the 19th Century. At the same time, the arcade wall that was
altered in the Post-Medieval period was extensively renova-
ted. In making the capitals, the stonemasons appear to have
followed the historical examples exactly. In other parts ofthe
building Hase respected and preserved the historical con-
struction materials. However, he allowed old plaster and
distemper layers to be removed. Repairs and mortar replace-
ments were carried out using cement-containing putty mix-
tures and coatings, which lead to an acceleration of the dete-
rioration processes. Finally, a subtly differentiated stone-
coloured paint layer was applied to the treated surfaces to
even out variations in the colour ofthe repairs and the origi-
nal material.

Destruction and reconstruction after 1945
St. Michael’s church, like the adjoining cloister, was severely
damaged in World War II and thereafter rebuilt with diffe-
rent priorities in the monument maintenance programs.
While the church was reconstructed in its Ottonish form,
destroyed parts of the monastery complex were replaced by
new buildings. Parts ofthe Western arm ofthe cloister survi-
ving 1945 were left, and integrated into the reconstructed
buildings in 1952. At the same time, a modern structure was
added to the preserved parts of yokes 1—8, which strongly
diminished the cloister’s character. The restoration-monu-
ment maintenance measures concentrated mainly on the lar-
gely destroyed eighth yoke, which was reconstructed, to give
the connecting dragon-rib a suitable setting.

Architectural foundations and hydrogeology
In the course of the examination of the foundations and
hydrogeological conditions in the substrata of St. Michael’s
church, numerous boreholes have been made since 1938 and
a series of testpits have been dug. Some ofthese boreholes are
groundwater measurement sites. Samples of groundwater
were chemically analysed, to clarify the hydrogeological con-
the architectural surfaces, which the cloister received when it
