Můstek (Czech pronunciation: [ˈmuːstɛk]) is a Prague Metro station that serves as an interchange point between lines A and B, situated under the lower end of Wenceslas Square.

Each line has a separate set of platforms which are connected by a series of corridors.

[1] Můstek A has two exits through escalator tunnels (one on both ends of the middle aisle) with one vestibule below lower (NW) end of the Wenceslas Square where the preserved medieval bridge can be seen and the other below the central part of the square.

A system of corridors connects the station of Line A with station of Line B located roughly in the same location, but several metres deeper.

Můstek B has one escalator tunnel with a vestibule below Jungmann Square.
