The Chopin Bench in Tallinn, Estonia

This is no standard bench for sitting upon; It is interactive and plays music from Frédéric Chopin's concertos. 

Gifted to Tallinn by the Polish Embassy and unveiled on the 200th anniversary of Chopin's birth, the bench plays the opening section of the larghetto from Concerto No. 1 in E-minor, and the larghetto from Concerto No. 2 in F-minor. Similar benches can be found in Warsaw, Chopin's hometown.
