Torre Tall Hermann, Castelo de Toompea

Tall Hermann, the tower of Toompea Castle, was built in 1371.
A narrow stone staircase of 215 steps leads to the top of the tower where flies the national flag of Estonia. The blue, black, and white of the national flag were first seen here on 12 December 1918 and after years of Soviet occupation, again on 24 February 1989. The flag is raised at sunrise and lowered at sunset.

The Long Hermann (Pikk Hermann) is one of the four original medieval corner towers of the castle on Toompea Hill. It is considered one of the city's landmarks.
It was built as a tall and slender watchtower between 1360 and 1370 and extended to its current height of 45.6 m in the 16th century. Its top is 95 m above sea level. According to medieval tradition, the strong tower was called "Hermann". The Pikk Hermann is part of the Tallinn Castle, which is home to the Estonian Parliament (Riigikogu).

"It took close to one and a half centuries to await my completion, when in 1219 the Danish King brought into swing the construction of the city, here in the current Toompea, Tallinn (Reval). The wait was worth it! I am a flag tower, the most important one in the city and tower above all. My height is more than 80 metres, if you include the escarpment base and the height above sea level is more than 90 metres. There is no similar in the vicinity and hopefully also not further away. It is true that thanks to the expansion of the city, the current highest point in Tallinn, is now located in Nõmme!
My name means tall warrior or great chief! Kiek in de Kök obviously will argue that it is taller, but nobody can see that, as it starts to rise from within the ground. Kök is after all wearing a very tall hat, whereas I do not even have a roof. The open top level is for a reason, in my case. I repeat: I, as a flag tower am not only a symbol of the city, but of the entire country."
