St. Peter's Church contains late medieval murals of recognized high quality, as well as a number of unusual furnishings.

The church is actually dedicated to two saints, St. Peter and St. Paul, Ecclesia beatorum Petri et Pauli apostolorum.

The explanation is probably that Malmö rose to significance at a time when the land was already subdivided into parishes following the Christianization of Scandinavia in the preceding centuries.

[4] Malmö began a rapid expansion thanks to the lucrative trade in herring around 1200 and the city was part of the economic infrastructure around the Hanseatic League and the Scania Market.

[note 1][7][6] It is part of an urban structure with a still largely intact medieval street layout.

[15] A substantial reconstruction of the church was made in 1847–1853 under the guidance of Carl Georg Brunius.

The church was at the time in an unarguably bad condition but Brunius' renovation has nonetheless been criticized for having been harsh.

[18] The church was given an entirely new copper roof, and large parts of the walls were replaced with new bricks.

A large part of the ambulatory was entirely dismantled and rebuilt, and nearly all the buttresses of the church were heavily reconstructed.

[15] Between 1904 and 1906, cathedral architect Theodor Wåhlin tried to restore what had escaped destruction fifty years earlier.

Between 1965 and 1967 the interior of the church was renovated, and the murals in The Merchants' chapel carefully restored.

[19] The inside of the church is characterized by the tall nave, reaching 25 metres (82 ft) at the transept.

The walls, pillars and vaults are whitewashed, giving the interior a light and bright atmosphere.

The Merchants' chapel (Krämarkapellet) is richly decorated with late medieval murals.

[1][21] The murals cover both the walls and the vaulted ceiling, and display several different motifs, both secular and religious, set among a background of flowing, green vines.

It was made in 1611 by several local master carpenters: Jacob Kremberg, Statius Otto [sv], Curt Snedker, Öllrich Svarfer and Henrik Könnicke together with Didrik Moll [sv], a court painter in the service of Christian IV of Denmark, and the painter Pieter Hartman, a local resident.

In the lowermost part there is a depiction of the Last Supper in the centre, and on each side wooden sculptures of Moses and John the Baptist, respectively.

It was commissioned by a member of the city council, Engelbret Fris (or Engelbrekt Friis) and made by Daniel Thomisen [sv].

[22][23] The baptismal font is also made by Daniel Thomisen, and was commissioned by another city council member, Rasmus Ludvigsen.

The main organ in the west gallery was revoiced and three years later it was expanded with Soubasse 32', Basse acoustique 64' Chamade 16', 8' and 4'.

These are expanded in octaves, which thus allows a large number of transmissions and with the help of modern technology it is also possible to build your own voices and sounds in any way you want.
