When the first small drop of water falls over the edge of the dam, its foaming journey towards more spacious waters, towards the great lake of Ladoga begins. It first foams in the Imatrankoski Rapids and tries to escape the great water masses that follow. The drop swims under the old lanterns at Koskisilta Bridge. It spins past the idyllic Pavillion. It passes the venerable Valtionhotelli hotel and a rock cliff that in the past held a squeaky ropeway. It sprays some moisture on the guests standing at the viewing terrace and surges towards the centuries old rock engravings, the royal graffiti. And this is how the water masses accumulate. They fill the rugged channel; they spin, agitate, thunder. Visitor to Imatrankoski: If you have never heard the thunder of the rapids, experienced its magnificent force, now is the time. For a moment, you feel you are held tightly in the violent embrace of nature. For a moment, you feel you are one with history, with the ancient river bed. That experience is just as large as the smallest drop of the foaming rapids. The Rapids shows in 2024: June 26 - August 31 from Wednesday to Sunday at 6 PM.
