I'm wondering about the famous censored blob north of Katwijk. If you go
back a few years you can get a proper image of it, but it looked like just
houses. Has something secret been built since, or are they censoring
houses?

I found this news article (in Dutch) which basically says that the people
who
live in the area are unhappy because their houses are hidden beneath the
blob
and therefore want it removed.
