When it's not being used for the Song Festivalor, you know, revolutionsit's one of northern Europe's largest concert venues, with acts like Lady Gaga headlining.
But on a gorgeous sunny summer's day, it's also one of the prettiest places in Tallinn. The fantastic 1950s architecture is a joy just to look at, and the gently sloping grounds reach a remarkable height over Tallinn.
While in the Grounds, don't miss two things: first, the incredible acoustics of the performance steps, which have an amazing echo-chamber effect, and second, the singing bench at the top of the viewing grounds (behind the statue of Gustav Ernesaks) which plays songs by the Estonian National Male Choir.
But true music fans should come back in 2014, which is the next run of the quinquennial (yeah, we love that word too) Laulupidu.
