The relay station
The royal relay station of Ysle was founded mid-17th century, the postal road from Paris to Sedan, started in 1654, had a mandatory halt there; located between the halts of Reims and Rethel-Mazarin, it was an important link of the road to Sedan, a then predominant town of the Ardennes. At that time, the Galand family settled in Ysle and initiated a postmaster dynasty.
