The Acquario Romano (Roman Aquarium) is situated in Piazza Manfredo Fanti, Rome, Italy.

[1] Designed by Ettore Bernich and built between 1885 and 1887, the building hosted an aquarium for few years.

A typical building of the age of king Umberto I, it has a circular plan and shows a pronaos with aediculas.

Decorations with marine subject are inserted between the sculptures into the aediculas; between the caryatids are placed some medallions.

After a period of abandon, it was restored and used as a museum and seat for performances and concerts.
