The dates and sovereignties seem in order, but the map is modern no matter how far you go back. The boundaries shift, but the coastline remains in its 2024 state. This means historical seas are missing, and present-day polders are present in the middle ages, etc.

You can change maps to many older maps under the "Explore Maps" option on the home page of the site. it seems you can either explore maps or history, but not both at the same time.
