What does this number measure?
Four curved legs, arches and three levels form its actual silhouette. Displayed dimension: total height including the antenna.
Compare the stated dimensions
The comparison uses the number in each fact sheet: altitude, height, diameter, length or distance, depending on the reference. Two values in metres do not necessarily describe the same property.
Source and limitations
Dimension checked in a primary source that was consulted.
Detailed interpreted illustration. It is not a photograph, an architectural survey or an exact scientific reconstruction.
Opening: 1889. Proposed historical date; an existing documentary source is linked but was not consulted for this date in this session. Do not interpret this reference as the manufacturing date of the illustrated specimen. The total height including the antenna shown today also results from later additions.
