The Tamme-Lauri oak is the thickest and oldest tree in Estonia. It was named after Laurits, the god of fire who is said to live inside the tree. The Tamme-Lauri oak is believed to be 700 years old, planted in the year 1326. Legend has it that the tree started growing from a carriage part that a Swedish king hit into the ground.
The tree has been hit by lightning many times over the centuries and has become hollow inside. Seven people can fit inside the trunk.
