I'm looking for an extension that extends the normal address fields with additional 'Regions': touristic, historical, ..

Extensions CiviCRM Region Lookup by Matthieu Lufty - https://github.com/mlutfy/ca.bidon.regionlookup

Area / Region by Jaap Jansma - https://lab.civicrm.org/extensions/org.civicoop.areas

Seem to be doing the same thing, but are not doing what I need.. 

I disabled both of them after seeing below warning in the Log File:

After running composer update my sites break with error 'The "broken" plugin does not exist.'

composer is updating doctrine/deprecations from 1.1.3 to 1.1.4  and this causes the issue.

Resolved by downgrading this module with composer require doctrine/deprecations:1.1.3
