Great springs, Natural monument in Bazarnosyzgansky area, Ulyanovsk Oblast, Russia.

Great Springs is a water source in the Bazarnosyzgansky area of Ulyanovsk Oblast that feeds several rivers and supplies water to local communities. These natural springs emerge in an inhabited region where they play a role in the overall water system.

The springs supplied drinking water to the Syzgan sloboda, founded in 1638 as a border guard post on the approaches to the Simbirsk-Karsun defensive line by streltsy sent from Moscow. During the Second World War a military unit stood above the springs; soldiers drew water and posted a guard at night. In 2017 the site was improved on the initiative of the Ulyanovsk Oblast administration and the Bazarnosyzgansky district municipality.

The springs gave drinking water to the Syzgan sloboda, founded in 1638 as a border watch post on the Simbirsk-Karsun defensive line. During the Second World War a military unit stood above them, and soldiers drew water and posted a guard at night. The water leaves no scale when boiled and keeps its taste for a long time.

The site sits in a settled area and is accessible to visitors, though you should respect protection measures in place. It helps to learn about local rules beforehand to avoid disturbing the springs or their surroundings.

The water leaves no scale when boiled and keeps its taste for a long time; its density of 980 kg/m³ indicates an absence of salts. Two smaller springs beside the main outlets never dry up.
