In brief:
On this page I try to make an overview of Foucault pendulums in the Netherlands.
If you know one which is not mentioned here, please send me a mail.
Permanent Pendulums:

Lattrop, Cosmos observatory. This pendulum was made by Piet van der Hoeven.
Oldenzaal, Thij College.
This Piet van der Hoeven also built a pendulum in the Thij-college in Oldenzaal. Video
I have made a separate page for this one because it has some interesting details.
Temporary Projects / Demos:
Veere, Grote Kerk. Not verified. From hearsay that it was a temporary project.
