House of Questions

Delphi House of Questions was an EU Culture 2000 project by three EXARC members. Under this umbrella, other EXARC members as well collected and answered the most frequently asked questions by visitors to archaeological open-air museums. The largest part of this collection of questions you can find here – as many of them still carry importance. In most cases we offer the questions both in the original language and in English.

How is wood tar made (NO)?

Tar is made by placing pine roots in a conical hole in the ground, lined with birch bark. They are then covered by turf, and set on fire. The turf keeps the oxygen out, so the wood doesn’t go up in flames. The sap is boiled out of the roots and runs to the bottom of the hole, where it can be collected as tar.
