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:
Nijmegen, Radboud University, Huygens building.

Veere, Grote Kerk. Not verified. From hearsay that it was a temporary project. But it seems to be permanent now.

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:
Brouwershaven, Grote Kerk. Not verified. From hearsay that it was a temporary project.
Haarlem, St Bavo church. By times they do a single demonstration.
