Glaskubus, Holocaust memorial monument in Planken district, Mannheim, Germany.
The Glaskubus is a monument made of four vertical glass panels forming a three-meter cube, rotated 45 degrees toward the center of Paradeplatz. Its interior surfaces are covered with 2,280 engraved names arranged in a dense, overlapping pattern throughout the structure.
The monument was erected in 2003 and commemorates Jewish citizens from Mannheim who were persecuted and killed during the Nazi period. Its establishment reflected the city's commitment to making this remembrance visible in the public sphere.
The engraved names on the interior glass panels appear as mirror writing when viewed from outside, creating a reflective visual experience. This arrangement encourages visitors to engage actively with the inscriptions and interpret them in a personal way.
The glass cube is freely accessible during the day and night, with nighttime lighting making the names clearly visible. Visitors can approach the monument from any side at any time without scheduled hours or special arrangements needed.
The structure was deliberately designed as a transparent cube to keep the victims visible rather than hidden away. This integration into the daily life of the city means the memorial serves as a constant reminder while remaining part of the living public space.
