Blaisy-Bas can be explored through its railway history, the village’s architectural heritage and its distinctive landscape. The tunnel on the Dijon–Paris line, the Saint-Rémi parish church and the source of the Oze offer specific points of interest. The commune also lies within the ZNIEFF area “Val de la Drenne et coteaux entre Charencey et Dree.” A seasonal event featuring historic vehicles adds a specific date to the calendar. This makes it possible to explore the area according to your interests in technology, history or nature.
Railway and Local History
The Blaisy-Bas tunnel on the Dijon–Paris line is 4,110 metres long; its two tracks were built between 1846 and 1849. The self-guided tour “Blaisy-Bas sur les rails du temps” (Blaisy-Bas on the Rails of Time) also puts the railway theme front and centre in its name. It was devised by pupils at the Blaisy-Bas school. The tour is available through the free GUIDIGO app; once downloaded, the route can be followed from the stated starting point without an internet connection. If you plan to include this digital tour in your itinerary, check the availability of the app and route before travelling.
Building History in Several Stages
The Saint-Rémi parish church reflects a history of construction in several stages. It was built at the end of the 15th century or the beginning of the 16th; alterations followed in the 17th and 18th centuries. The church was restored between 1897 and 1899. A sundial dating from 1661 adds a precisely dated detail to this timeline. This makes it possible to distinguish chronologically between the original construction, later alterations, the restoration and a historic feature.
Other Traces and Landscapes
The village’s history is also reflected in other named buildings and historical traces. Blaisy-Bas once had as many as six washhouses. An oil mill, built at the beginning of the 19th century, is also located in the village. Traces of an old, small stone basin remain at the Fontaine Saint-Julien. In addition, there are the ruins of a building called Château Lorrain. These examples range from washhouses and a mill to remnants of a fountain and ruins, complementing the view of Saint-Rémi with other local points of interest.
The Oze rises in Blaisy-Bas; the commune also lies within the ZNIEFF area “Val de la Drenne et coteaux entre Charencey et Dree.” These are two distinct landscape connections: the river is linked to Blaisy-Bas by its source, while the second statement refers to the commune’s inclusion in a named area. This adds a nature perspective to the village’s architectural and railway history.
Exhibition in the Seasonal Calendar
Méca Passion 21 organises a free exhibition of historic vehicles in Blaisy-Bas. In 2026, it is scheduled to take place from March to October, on the third Saturday of each month. The exhibition venue is the Esplanade on Rue Chaignot, 21540 Blaisy-Bas. If you plan to visit the exhibition, check the specific date again before travelling. The seasonal schedule offers an initial guide; for planning purposes, the date for the relevant month is what matters.
