Hi @conradt , cool !!! Rotterdam and Amsterdam. Rotterdam is great for its harbour,it is a touristic thing but great to experience. You can do great tours. Amsterdam has a lot of great things like the Rijksmuseum (if you like agient painters) ,but almost anything in Amsterdam is touristic 😂 ... in Zeeland you have the deltawerken,thats not to far from Rotterdam, those are the systems that avoid holland from flooding when waters run high..very impressive... my name is verhp11 on discord :)
