On the north side of City Hall on the Grote Markt, you’ll find the bust of commander Carl von Rabenhaupt who is famous for many reasons including his giant curly wig. It's probably the only statue of a German commander on a Dutch building and it was placed there to commemorate the Franco-Dutch War, or to be more specific, the Siege of Groningen in the year 1672. Today, August 28 is a local holiday, better known as Bommen Berend Day, which is named after the leader of the 22,000 strong army of the Bishop of Münster, that tried to capture the city, unsuccessfully. He was nicknamed Bombing Bernard for shooting more than 5,000 bullets at the city in only a month's time, which we gather was quite a lot back then. German-born Carl von Rabenhaupt was the fearless commander of the city of Groningen. Although officially retired, he was put in charge of the Dutch defences and personally made sure that the attacking Catholic army never entered the city.
