Tallinn Bastion Tunnels

Underneath the Toompea bastions is a network of tunnels. Several hundred meters of which has been cleared for visitors. Rumor has it that the entire old-town has a network of underground tunnels, but no-one knows for sure.

The final section of this particular tunnel is still flooded, this section is cut off by the "Mayeri trepp" (a staircase going up the hill).

For more information about visiting the tunnels see the Kiek in de Kök Museum. There is/was also a bar in a tunnel in the Old Town (not accessible from the museum's tunnel).
