I visited this WHS in November 2014. I confess I'm not a fan of industrial heritage sites in general and so I wasn't too keen to visit this WHS. Yet I was pleasantly surprised with the way the visit is structured and even though you're not allowed inside the shoe last plant itself, the curtain wall windows easily allow any visitor to see the employees at work producing shoe lasts. In fact I'd recommend visiting on weekdays if possible to avoid seeing an empty factory. I also bought the new Fagus Factory 60c stamp and an interesting addition to my WHS library "Deutschlands Welterbe: Eine Reise zu allen UNESCO-Stätten" from the gift shop. All in all I think the Fagus Factory is a worthwhile stop on your way to Hildesheim or Corvey Abbey.
