The map shows documented sites of the NSU complex. Each point represents a
location; the colour indicates the category:

- **Whereabouts** – residences and meeting points
- **Supporters** – people and structures of the network
- **Robberies** – scenes of the robberies
- **Murders** – scenes of the murders

Use the filters above the map to show or hide individual categories. Clicking a
point opens a short info box with a link to the detail page.
