A Foucault pendulum in Mainz is listed on Wikipedia. The article says that it is in

School for Business and Technique, Mainz

However, I didn't find any information about this pendulum on the Internet. I know that this question is not fully in the profile of this site, but maybe someone know that

where exactly is this Foucault pendulum and when is it visitable.

    $\begingroup$ Could that be a mixup with (or move to) nearby Frankfurt am Main, where the Experiminta Museum has one, half an hour away and missing from the wiki list? $\endgroup$ Oct 21, 2018 at 18:01
  • $\begingroup$ Google books led to a novel: Title Das Mainzer Mörderpendel Author Jean C. Becker Publisher Selztal-Verlag, 2005 ISBN 393692905X, 9783936929058 Length 187 pages $\endgroup$ Oct 21, 2018 at 20:18
  • $\begingroup$ Searching German websites, I cannot find any "{Fach}{hoch}schule für Wirtschaft und Technik" in Mainz. The closest match to the description might be "Hochschule Mainz / University of Applied Sciences". However, I an unable to find any mention of a "Foucault-Pendel" or "Foucaultsches Pendel" in this school or in fact anywhere in Mainz. The Wikipedia entry would appear to be out-of-date or in error. $\endgroup$

    $\begingroup$ I grew up near and studied at the University in Mainz and I have never heard of a Foucault pendulum at any school or the university. That doesn't settle this question definitely, but I would be very surprised.. $\endgroup$

Summary of comments, per OP’s request:

  • As observed by @njuffa, there is no apparent trace of a Foucault pendulum at (closest match) Hochschule Mainz’s School of Business (Wirtschaft) nor School of Engineering (Technik).

  • Could it, then, be a mixup with — or relocation to — nearby Experiminta Museum in Frankfurt am Main, which does have one, half an hour away and missing from the wiki list?
