The Kiek in de Kiek Fortification Museum and its underground tunnels and defense towers offer experiences and a unique opportunity to get to know the history of Tallinn, while moving from one tower to another along the old city walls. The Kiek in de Kiek Fortification Museum consists of three interlinked parts:
1) Kiek in de Kiek's artillery tower
2) The underground bastion passages and the carved stone museum
3) The maiden tower (Neitsitorn), the Stable Tower (Tallitorn) and the Gate Tower (Väravatorn).

Please see the opening hours on the Fortress Museum website. The museum is closed on Mondays.

Unfortunately, the museum is not suitable for the disabled due to a large number of stairs.
