1799-1801, architect A.N. Voronikhin
1854-1857, architect A.I. Stackenschneider
According to the plan of Peter I, every palace in the Lower Park had to have a matching cascade. So the idea of building a new cascade next to the Hermitage, appeared simultaneously with the construction of the pavilion itself. The initial draft of this fountain construction, was made by the architect N. Michetti, in 1720, but the project failed to be implemented. Peter's idea of creating the cascade was embodied only in 1801, when not far from the pavilion, the Hermitage cascade was built by the design of the architect A. Voronikhin:the pool with waterfall ledges of Pudost stone, decorated with two bronze sculptures of guarding lions, cast by the model of I. Prokofiev. The cascade was starting to be called "The Hermitage" for its location or "Lions" - for the decor.
In the 1850's, the Hermitage cascade was dismantled due to its heavy destruction. In its place, a new cascade was built by the project of the architect A. I. Stackenschneider, which preserved the name of the "Lion Cascade". The former sculptures of the lions were placed on both sides of the colonnade, made of granite and marble. In the center of the basin, on a granite rock, there is a statue created by the model of F. P. Tolstoy, of the nymph Aganippe - the patron saint of the eponymous wellspring at the foot of the Helicon mountain. According to the legend, people who drank from this source, were poetically inspired.
The Lion cascade is the only one of the four cascades of the Lower Park, that is not located on a slope, but on the lower terrace. The restoration of the Lion cascade in 2000, completed the post-war rehabilitation of the Lower Park fountain constructions.
