Echo Grotto

The Echo Grotto is located on the slope of a hill near the shore of the Silver Lake in the Palace Park of Gatchina, and the remains of a semicircular stone pier have been preserved on the shore next to it. Thanks to the good acoustics, the echo in the grotto can repeat up to four syllables, and the most impressive effect is achieved at the second pair of lanterns from the entrance, where the sound repeats up to 30 times. The entrance to the underground passage from the side of the grotto is closed by an arched iron door, since the lake is used for water supply and a sanitary zone has been established around it. In the post-war period, the space of the underground passage was used as a warehouse for the city trust "Vodokanal".
