Along the federal highway B9 south of Brey stands a Prussian milestone from 1820.

The erection and design of the milestones along the country road by the Rhine from Koblenz to Bingen took place as part of a comprehensive road construction program in the Rhineland, including surveying by the Prussian state. The milestones were created based on model designs from Berlin: a four-sided obelisk made of basalt lava, tapering to a point at the top, with benches added on both sides. The distance indications to Cologne, Koblenz, and Mainz are engraved in Prussian miles on the roadside view surface.

In addition to the milestone in Brey, milestones have been preserved in Boppard, in St. Goar-Fellen, as well as south of Oberwesel and south of Niederheimbach.
