Ancien observatoire astronomique de la Marine de Nantes
Ancien observatoire astronomique de la Marine de Nantes, Naval astronomical observatory in Nantes, France
The observatory features a 27-meter-high tower with a square base and a terrace roof, accessed through a staircase of 127 steps.
Built in 1826 by architect Étienne Blon, the observatory served as a training facility for naval navigation and astronomical measurements until 1887.
The observatory represents an important part of French maritime education, where students learned celestial navigation techniques essential for seafaring expeditions.
Located at 18 Rue Voltaire in Nantes, the observatory remains a private property and requires advance arrangements for visits.
The structure stands as the only intact naval astronomical observatory in France specifically constructed for maritime observations.
