The library was rebuilt with American aid. If you walk around the building today you will see all the plaques of contributing institutions embedded in the walls.
In August of 1914, during World War I,
Leuven was looted by German troops. In
the night of the 25th to 26th of August,
they set fire to a large part of the city,
effectively destroying about half of
it. The Germans set fire to the 14th
century University Hall and its library
wing. The University library burned,
and with it about 300,000 books, about
1000
incunabula and a huge collection of
manuscripts, including the University’s
founding bull from 1425.
The Germans had aimed to punish
Leuven after alleging the presence of
snipers in the city. They claimed that
the sacking of Leuven was a fair reprisal.
Their ‘punisment’ of Leuven destroyed
more than 1000 buildings and cost more
than 200 lives.
When war broke out in Europe in September 1939, soon after the restoration of
Leuven’s new library, Belgium found itself neutral once again.
After the retreat of the British and
with German forces entering the city, on the 17th of May 1940 the new University
library was set aflame after an artillery barrage. Molten glass from the above
floors flowed into the cellars, past the steel doors, and destroyed the collections.
The entire building was gutted.
Not even twelve years after its opening, the new University library was reduced
to rubble and its collections were ravaged once more. The occupying forces
accused the British of having set the library ablaze on purpose to allow them to
later blame the Germans. No access to the ruin or objective investigations were
allowed. Joseph Goebbels, German propaganda minister, paid the ruined library
a visit to push the German version of events. At the Nuremberg tribunal it was
found that the library burned after German artillery had struck it.
Only 21,000 of the original 900,000 pieces in the library collection were left.
Hundreds of manuscripts (including some that had survived the 1914 fire) and
everything from before 1501 was destroyed.
