Obelisk of Saint-Vrain

Highlight • Monument

New lord of Saint-Vrain since 1747, Louis DUVAL DE L’EPINOIS undertook in 1750 to build this obelisk in a room of 55 acres facing the main alley of the castle. Several alleys left from it in a star shape.
This monument was not erected for the completion of work concerning the tracing of the Paris Meridian and the triangulation of Jacques de CASSINI (work continued by his son César-François for the determination of the geography of France).
However, it is nevertheless thought that the place where the obelisk is located could have been a point of one of the local secondary triangles, during the verification of the basic triangulation (1740-1744) in order to increase its precision. DUVAL DE L’EPINOIS being very sensitive to this work, this monument is therefore only a “memorial monument”.
