The commune's defining feature is the Sources de la Seine, a landscaped public park spanning 2 hectares on the Plateau at an elevation of 446 meters, where seven springs emerge to form the nascent river.

In terms of spatial extent, the shares boundaries with several neighboring areas, such as Frôlois to the northwest and Chanceaux to the north; prior to the 2009 merger with Blessey forming the current , Saint-Germain-Source-Seine adjoined Blessey as a distinct spatial neighbor.

Hydrology and the Seine Source

The Seine River originates from a primary spring located within the commune of Source-Seine, emerging at an elevation of 446 meters in the wooded Côte Hill area on the Plateau. This modest spring forms the initial small stream that gradually develops into one of France's major waterways, extending for a total length of 777 kilometers and ranking as the country's second-longest river after the . The spring's emergence in this elevated, forested setting underscores its role as the hydrological starting point for the river's northeasterly course toward the . Hydrologically, the Seine's source is characterized by its karstic origin, drawing from underlying limestone aquifers that filter through permeable formations, yielding clear, calcium-rich outflow. These aquifers, part of the broader systems in the region, facilitate groundwater circulation via dissolution-enlarged conduits at the contact between permeable limestones and underlying impermeable marls or clays. The primary serves as the dominant contributor to the nascent , distinguishing it from nearby secondary springs that occasionally augment flow during wet periods; the initial stream's modest volume reflects the plateau's subdued drainage dynamics before downstream tributaries significantly increase discharge. Geologically, the Plateau's bedrock—encompassing Bajocian and oolitic and reefal limestones—underpins the spring's formation, promoting karstic dissolution that enhances permeability and . This matrix imparts the source waters with notable content, including elevated calcium levels, while the plateau's gentle dip toward the northwest directs subsurface flow toward the emerging . The resulting hydrological regime supports a stable, albeit variable, from the , essential for the Seine's early development amid the region's temperate . The source area has been recognized as a protected natural site since the mid-19th century, reflecting its ecological and symbolic importance. In 1864, under Emperor , the City of acquired the property and established the Domaine des Sources de la , commissioning landscaping and a symbolic to preserve the site's integrity and accessibility. This designation ensures ongoing conservation of the spring and surrounding woodlands, safeguarding the aquifer's recharge zones from development pressures.

History

Prehistoric and Ancient Significance

Archaeological investigations in the Upper Seine Valley have revealed evidence of human activity dating back to the period, with early settlements likely drawn to natural springs in the region for and purposes. Sites in the region show occupation from the Early onward, indicating that the area's hydrological features attracted prehistoric communities for practical and possibly symbolic reasons. However, specific Neolithic finds at the exact Source-Seine location remain limited, with more substantial evidence emerging from the . During the period in the , the Source-Seine emerged as a major pilgrimage center dedicated to , the goddess of the River, revered for her healing powers associated with the spring waters. Pilgrims from across traveled to the site to offer artifacts, seeking cures for ailments or expressing gratitude for recoveries, with over 1,500 such votive offerings discovered in excavations spanning 1836 to 1967.

Local traditions adapted ancient rituals through the of Saint Seine, drawing regional pilgrims seeking relief from ailments. During the feudal era (11th–18th centuries), the Sources de la Seine area fell under the influence of local lords and ecclesiastical authorities, particularly the Abbey of Saint-Seine, which held dependencies including agricultural lands in the vicinity. Ownership shifted among Burgundian nobility, with the plateau's calcareous soils supporting expanding agriculture through three-field rotations and communal grazing, fostering population growth and rural self-sufficiency amid the Duchy of Burgundy's economic rise. Pilgrimages to the springs persisted, blending folk Christian practices with the site's reputed therapeutic waters, though now framed within saintly intercession rather than pagan rites.

This merger sought to consolidate administrative resources and safeguard the rural heritage of these small communities facing viability challenges. The new entity received 21084, reviving the historic name Source-Seine to emphasize its geographical significance. Following the merger, minor boundary adjustments were implemented to enhance administrative efficiency, integrating the two hamlets—Saint-Germain and Blessey—under a unified municipal structure with the town hall located in the former area. In recent years, amid ongoing rural depopulation trends in the region—where nearly two-thirds of intercommunalités lost residents between 2015 and 2021—Source-Seine's has stabilized at 60 inhabitants as of 2022, supported by local preservation initiatives.
