Kiek in de Kök

Built in the 15th century, this 45 metre, six-storey defensive tower is home to a fascinating museum of Estonian history and several floors of contemporary art. On the exterior of the tower lookouts are nine of Ivan IV's cannonballs embedded in the wall, left there as a reminder of the medieval-era Livonian Wars.

Toompea Castle

Actually a 20th century building with a pink Art Nouveau façade which is home to Estonia’s parliament.

The Song Grounds

One of Estonia's most important cultural sites; in 1988, 300,000 Estonians gathered here to sing the banned national anthem, an event that was subsequently dubbed the Singing Revolution, voicing their discontent at the Soviet occupation. Nowadays the Song Grounds are used for large concerts by such famous performers as the Rolling Stones and Michael Jackson, the Beer Festival and the National Song and Dance Festival, which is held every four years.
