4. CHANGES IN THE 
STRUCTURE OF 
THE ROOF TRUSS 
In connection with the roof renovation 
the roof truss has been exactly measured 
and drawn in the form of floor plans and 
sections to document the damages (Fig. 
9). At the same time these drawings 
serve as basis for the historical investi 
gations. Dendro-chronological examina 
tions provide accurate details of the con 
struction date of particular sections. 
Summarizing all these aspects we can 
describe the condition of the roof con 
struction in connection with the Baroque 
bell tower (Fig. 10). This way the 3- 
dimensional model illustrates the inter 
vention in the Gothic roof structure.
