La Ferté-Milon station has rail connections to Meaux and Paris.

In La Ferté-Milon stand the ruins of an unfinished castle, whose façade was 200 m long and 38 m high.

The singular form of the tower walls was probably designed to resist cannons and protect the gate.

A statue of Racine as a child is located at the bottom of the paved Ruelle des rats.

Nearby is a slate-roofed church with a square belfry with four turrets in each corner, one of which serves as a staircase.
