In a number of Dutch towns city tours are being offered with a focus on the history of the town with specific links to slavery and colonialism.
Since November 2011 you can participate in the walking tour Traces of Slavery in Utrecht. For more information look at the website Sporen van Slavernij Utrecht for more information. For a guided tour you can contact the organizers by mail.
In Amsterdam initiator and guide Jennifer Tosch offers the Black Heritage Amsterdam Tours on a weekly basis since 2013. For information and bookings see Blackheritagetours.com.
