Christianshavns Vold is a former rampart which was part of the bastioned fortification ring which used to surround Copenhagen, Denmark.

Running along the full south-eastern perimeter of Christianshavn and Holmen, it used to form a protective barrier towards the island of Amager.

It consists of earthworks with 12 bastions and in front of it ran a moat, Stadsgraven, now forming a broad canal which separates Christianshavn from the rest of Amager.

on Amager, was a lower system of outworks called Christianshavns Enveloppe of which only the northern half survives.

The southern half of the rampart is a municipal park whereas the northern portion is part of Freetown Christiania, a self-built, semi-autonomous community which has existed since the early 1970s.

Part of Christiania is located on the far side of Stadsgraven and the two halves are connected by the Dyssebroen footbridge.

The rampart was constructed with four and a half bastions and a city gate, known as Amagerport, through which all traffic to and from Amager had to pass.

From 1682 to 1692 Christianshavns Vold was again extended this time in northwards, to guard the entrance to the harbour and protect the new base for the Royal Fleet at what was to become known as Nyholm.

Kalvebod Bastion takes its name after Kalveboderne, the shallow waters which were located to the south of Copenhagen in what is now its Southern Docklands.

The bastion contains a gunpowder magazine from c. 1675 which was formerly used as a storage space by Copenhagen Municipality's park authority.

A combined distillery and tavern—frequentved by the many Dyrch farmers from Amager who came to Copenhagen on market days to sell their produce on Amagertorv—was also located on the site.

In the late 18th century, Peter Rabe Holm constructed a small beer brewery on the site.

The adjacent double house from 1802 to 1914 was listed in the Danish registry of protected buildings and places in 1988.

It received its name after Prince William of Denmark, a son of Christian V by Queen Charlotte Amalie.

It was named after Crown Prince Frederick, Christian V's son by Queen Charlotte Amalie, who succeed him in 1744–45.

The building, which is known simply as Frederiks Bastion, is used as a venue for exhibitions, concerts, workshops, meetings and other events.

The two former gunpowder magazines at Frederiks and Carls Bastions serve as venues for small concerts and art exhibitions.
