Kiek in de Kök Fortifications Museum and Bastion Tunnels

Kiek in de Kök is a 15th-century artillery tower at Komandandi tee 2 on Toompea in Tallinn, Estonia, whose Low German name means peek into the kitchen, because soldiers on its upper floors could look down into the chimneys and kitchens of surrounding houses. The tower is about 38 metres tall with walls up to four metres thick, and cannonballs from a 1577 siege by Ivan the Terrible's army are still embedded in the masonry. Inside, the museum run by the Tallinn City Museum presents exhibitions on the development of the city's defences, medieval weapons and artillery, and the history of the town wall, spread across several floors connected by steep stairs. A rooftop level gives views over the Lower Town. The ticket structure allows several options: a full museum ticket, a four-towers ticket that also covers nearby wall towers, and separate tours of the bastion passages. The bastion tunnels are a network of 17th-century casemates and corridors built into the earthen bastions beneath Toompea, used later as shelters, and they are visited on timed guided tours. A visit to the tower takes about one hour, and adding the tunnels brings the total to two hours. The best vantage point is the upper floors and roof, and a good photo angle comes from the Danish King's Garden and the path along the wall below, which frames the tower with Fat Margaret and the Neitsitorn tower. Crowds are lighter on weekday mornings and heavier when cruise groups arrive in summer. The tunnels stay cool throughout the year, so a jacket is useful. Opening hours differ between May to September and October to April, and the museum is closed on Mondays in the low season, so the schedule is worth checking before travelling to the site.
