What does this number measure?
Fifty metres from one end of the pool to the other. The comparison follows the length of a long-course pool. It does not include poolside areas, stands or other swimming facilities.
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
Catalogue order of magnitude; a source is provided, but this measurement has not been individually audited.
Detailed interpreted illustration. It is not a photograph, an architectural survey or an exact scientific reconstruction.
Generic construction: Varies by period. 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. Generic field or pool: no precise installation or construction date is identified. Dimension rules have their own history, distinct from a construction year.
