Restoration at a glance

Reportage (full movie)

Jan Klaassens, Hilko Hof and Arie Burggraaf from amateur video club Spotlight in Hoogeveen have made a documentary and reportage of the entire restoration (2012-2014). This REPORTAGE of the restoration (33 minutes) follows almost all restoration work in chronological order.

The various work activities can be viewed also as thirty-two individual short film fragments (on average 1 minute) in the toggle menu under the reportage.
