Libeskind’s five-story addition slices through the 1873 arsenal that houses the museum.

Studio Daniel Libeskind’s new home for the Museum of Military History in Dresden, Germany, opened to the public on Saturday. Set in the middle of a sprawling decommissioned military complex north of the city’s historic center, the museum is housed in a former arsenal building, which Libeskind has renovated and expanded with a v-shaped shard that rises 100 feet above grade. The glass, concrete, and steel triangle cants up and out from the center of the existing building, appearing to slice through it.
