The Old Post Office just outside Slavkov (Austerlitz) is the place where Napoloeno explained how he intended to fight the battle that was fought a few days later on 2 December 1805. Before the battle, this position was abandoned and the Russian General Bagration made it his HQ. After the battle Napoleon returned to the Post Office where he sent a message to his wife Josephine and then slept there. To the rear we can today see the monument to the fallen horse.
The Post Office dates to 1785 and the former stables are still visible today.
