Můstek (Czech pronunciation: [muːstɛk]) is a Prague Metrostation that serves as an interchange point between lines A and B. Each line has a separate set of platforms which are connected by a series of corridors. After the excavation of the area, a medieval bridge was discovered and the meaning of the area name Můstek ("Little Bridge") was fully understood.
Můstek A (completed in 1978) 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 (completed in 1985) has one escalator tunnel with a vestibule below Jungmann Square.
