M3 + M4 · Újpest-központ ↔ Kőbánya-Kispest
Opened 31 December 1976
Two metro stations lie beneath Kálvin tér, the square named after John Calvin where districts V, VIII and IX meet. The blue M3 platform opened on 31 December 1976 with the line's very first section, from Deák Ferenc tér to Nagyvárad tér; the green M4 station followed on 28 March 2014. At 28.24 m below street level, the M3 hall is the deepest station on the north–south line: a deep-level, six-tunnel design with a central island platform.
Four escalators climb to the Kálvin tér underpass, and the transfer corridor to the M4 leaves from the Corvin-negyed end. In the 1970s planners expected the M4 to run deeper, so this tunnel was dug downwards; the M4 ended up above it, so changing lines now means going down first, then up a long escalator. The M3 station was closed for renovation from 7 November 2020 to 13 May 2022.
Position on the M3 line:
Kálvin tér is a busy junction on the Small Boulevard (Kiskörút), right where the inner city meets the Józsefváros and Ferencváros districts. The Reformed church stands on the square, the Hungarian National Museum is a short stroll up Múzeum körút, and Vámház körút leads down to the Great Market Hall, the city’s largest covered market. Expect a mix of students, museum-goers, market shoppers and plenty of people simply changing between the M3 and M4.

The M3 station opened on 31 December 1976 as one of the six stations on the blue line’s first section. The M4 platform came much later: it received its operating permit on 30 December 2013, the seventh on the line to do so, and welcomed passengers when the M4 opened on 28 March 2014.
