Bau 36
architectural structure

Bau 36 (also known as Ernst-Abbe-High-Rise or Zeiss Building 36) is a historic high-rise located on the former factory grounds of Carl Zeiss AG in the west of the city of Jena, Germany.
Building 36 was erected between 1934 and 1935 by Georg Steinmetz and Hans Hertlein. The high-rise consists of 15 floors and reaches a height of 66 meters. It is characterized by a simple reinforced concrete skeleton structure; the only facade decoration consists of windows framed with masonry elements executed in contemporary designs. A renovation took place in 1994.
Above the main entrance, the sculpture "Through Night to Light" by Joseph Wackerle is affixed.The building now houses the main administration of Jenoptik AG. On the occasion of its 20th company anniversary in 2011, they installed a show laser in the opposite Building 15, which has since been used to project laser displays onto the building during certain events.

Why this record matters
The phrase “architectural structure” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated May 26, 2026. The linked authority identifier is Q811083. Authority coordinates are 50.928, 11.581. 1 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1934, 1935, 1994 and 2011.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
