Content objects Map view of addresses
This allows you not only to display but also to filter several addresses (of persons or institutions).

Allows multiple or individual addresses to be displayed on a map
Unlike the location feature, multiple addresses can be displayed on an OpenSteetMap map and the display can be specified by the user. For this purpose, address records of the type institution or person page record are used. This is somewhat more cumbersome when creating, but in future location changes can be made in one place for the whole system. In the map content object, a list view is generated next to the map for addresses of a certain file record tree. The results of this list view and the map section can be narrowed down further by means of a postcode search, and further filters can be programmed as required.
This feature is based on this extension:
wwt3_address
Previous version (without address link) already used in TYPO3 versions:
