Welcome to Cybis Dendrochronology and History!

Now we launch our new pages about various aspects of dendrochronology.
Try the tabs under "Tools and basics" if you are new to the topic.

We would like to push for some interesting news about our chronology project which has progressed to the next phase. Read more under the tabs "Dendro audit" and "Ancient history".
Also our "Local history" about dendro-dating in the Stockholm archipelago has been updated.
A search-function which covers the whole new site is available on each page.
