Another place visited during open monuments day in #Rotterdam was the so-called 'bouwcentrum', once the birthplace of my current employer IHS. The bouwcentrum was established as the central node in the post-war reconstruction of Rotterdam. It is a gorgeous building that favors form over function. IHS was born here, but moved to the university's campus some 20-odd years ago. The bouwcentrum is now in use as the head quarters of a sustainable energy company.
