The Pétrusse Casemates date back to 1644 when the
Spanish reinforced the existing medieval fortifications.
The Beck Bastion - named after the Governor Baron Johann
von Beck, a Luxembourger who had played a key role on the
side of the Emperor in the Wallenstein affair - was built
under the supervision of the Swiss fortress
builder Issac von Treybach. The bastion was raised to it's
current height of 27 meters (the same height as Constitution
Square) in 1685.
The Spaniards also built in "Ravelin du Pâvé" which
stregthened the Beck Bastion and this triangular fortification
is one of the best preserved fortifications in Luxembourg.
After the French laid seige to and conquered Luxembourg,
Marshall Vaubin redesigned and strengthened the defences
of the city which provided much of the present shape of the
Beck Bastion. Vaubin was also responsible for the building
the "Small Staircaase." The Austrians added the "Bourbon
Lock" and the "Large Staircase" and the 54
gun emplacements of the "Pétrusse Battery were
added in 1746. Over the following century the fortress was
enlarged and reinforced through the addition of a second
ring and a third ring was started.
After the Second Treaty of London, in which Luxembourg was
declared neutral, much of the Casemates where dismantled
and the loopholes and entrances walled up.
