The Tamme-Lauri oak was named after Laurits, the god of fire, who was said to live in the oak. The oak was featured on the back of the Estonian ten kroon banknote. A legend says that the tree started growing from a carriage part that a Swedish king hit into the ground! The oak has been hit repeatedly by lighting, damaging the branches, and the center had become hollow. Seven people could stand inside the tree. Tamme-Lauri oak is the fattest and oldest tree in Estonia.
