Petyayarvi north from Saint Petersburg, Russia, October 5, 2025
A rare view underneath the Visconti Bridge, revealing its dual function as a dam (plotina). The metal sluice gate system shown here is what controls the water level of the Slavyanka River. By regulating the flow through these gates, the park engineers could artificially raise the water level upstream, creating the wide, mirror-like "lake" seen in the previous images. Pavlovsk, a suburb of Saint Petersburg, Russia, October 6, 2025
Scattered, moss-covered remains of the pontoon bridge mechanism or its anchoring system. The massive granite boulders with embedded iron loops are likely anchors for a floating structure, or remnants of the pontoon system itself that was once used or stored near the Visconti Bridge. Before the stone Visconti Bridge was built in 1803, a floating bridge existed in this location. It is possible these are historical remnants from that era or parts of the hydraulic system used to manage the floating pontoons or secure boats near the dam. Pavlovsk, a suburb of Saint Petersburg, Russia, October 6, 2025

Red Cascade or Turkish Cascade in Catherine Park. The Red Cascade is a dam that regulates the water level between the Upper Ponds and the Great Pond. The two "towers" flanking the crossing are designed in the Gothic style, featuring red brick walls with white limestone details, pointed arches, and niche windows. It was built in the 1780s by the engineer Ivan Gerard, likely based on designs by the architect Vasily Neelov. Pushkin (former Tsarskoe Selo) near Saint Petersburg, Russia, October 10, 2025

Devil s Bridge (Chertov Most), also known as the Cascade, located near the Upper Ponds in Catherine Park.

Artificial waterfall on the Karasta River in Oranienbaum Park serving as a connection between the Upper and Lower Parks. It is a tiered spillway designed with granite steps that allow the water to cascade gracefully from the Lower Pond, flowing underneath a massive stone bridge (the Lower Bridge/Dam Bridge) Oranienbaum palace-and-park ensemble in Lomonosov (a suburb of St. Petersburg), Russia, October 13, 2025
Close-up view of the Karasta River cascade in Oranienbaum Park. The water tumbles over tiered, man-made steps (part of the Lower Bridge dam system), transforming into a silky, smooth sheet of water that suggests a long-exposure photograph. Moss-covered boulders at the base add a rugged, naturalistic touch, breaking the uniform flow into frothy white streams that contrast with the dark, wet stone walls. Oranienbaum palace-and-park ensemble in Lomonosov (a suburb of St. Petersburg), Russia, October 13, 2025
