The 289ft Bromo Seltzer Tower (1911) located in downtown Baltimore, Maryland was originally capped by a 20 ton laminated steel replica of a Bromo Seltzer Bottle with a Crown above the Bottle. The wording 'Bromo Selzer' were attached in relief around the bottle.
The 51ft x 20ft diameter Bottle and Crown were illuminated with 314 incandescent bulbs that could be seen from 20 miles away on a clear night.
The Bottle and Crown atop an octagonal cupola rotated on what is believed to have been a mechanical turntable. The Bottle and the top section of the Cupola was removed in 1936 due to structural concerns for the Tower's stability due to vibration from the Bottle's turntable.
General Description:
1. History (More)
2. The Project:
To reinstall a replica of the original Bromo Seltzer Bottle and Crown to the top of the existing Bromo Seltzer Tower.
The replica will be composed of two main elements:
The successful vendors will offer design solutions and supply design cost estimates to reinstall the Bromo Bottle and Crown meeting the following general specification:
a) The Cupola should be reconstructed to match the original and incorporate any structural
reinforcement that may be required to support the installation of the bottle and crown above.
b) The final structure of the Bottle should be as close as possible to the form and size (50ft x 20ft dia.)
of the original Bottle, with the proportion of the Crown to match. Sizes and Proportions can be
confirmed and calculated from available historical photographs.
c) The bottle's structural wireframe should be constructed of a light self weight material and construction.
d) The wireframe structure should be able of withstanding regional wind forces at a height of 289ft min.
e) The number of elements used in the wireframe structure should interface with the number of intersections required for attachment and support of the mesh cabling, power and control ribbons, and LED modules required by LED Lighting systems.

• GKD 'Media Mesh by GKD-USA Inc.
f) All elements must be capable of lengthy outdoor exposure under regional weather conditions.
