Manor
Kohala Manor
German: Tolks
Estonia's oil shale story has one of its starting points on Kohala land. Early in 1838, while digging a well in Vanamõisa village, people struck a stone that burned. Mining engineers of the St Petersburg Academy of Sciences analysed it in the laboratory and found that, when heated, it gave off a larger share of combustible gas than coal, and that it seemed suitable both as fuel and for extracting oil. Kohala itself was an old manor that passed through the Asseriens, Lodes, Tiesenhausens and Hastfers before returning to the Wrangells in 1801; its last owner was Sergei von Wrangell.

Eesti põlevkivi loo üks alguspunkte on Kohala mõisa maadel. 1838. aasta alguses avastati Vanamõisa külas kaevu kaevates „põlev kivim”. Peterburi Teaduste Akadeemia mäeinsenerid analüüsisid seda laboris ja leidsid, et kuumutamisel annab see protsentuaalselt rohkem põletusgaasi kui kivisüsi ning sobib nii kütteks kui ka õli saamiseks. Kohala ise oli vana mõis, mis käis läbi Asserienide, Lodede, Tiesenhausenite ja Hastferite käte, enne kui jõudis 1801. aastal tagasi Wrangellidele; viimane omanik oli Sergei von Wrangell.
