Fontaine de la Trinité, Historical fountain in central Toulouse, France.

Fontaine de la Trinité is a fountain whose wide, shallow marble basin rests on a central pillar bearing bronze statues of winged sirens, reached by three circular steps. Two winged creatures with coiled, fish-like tails flank the column, and water pours from a spout in a rounded stone block above a tiered octagonal base of pale stone blocks. The sculptures are by Louis-Alexandre Romagnesi.

The fountain was built in 1827 following architect Urbain Vitry's designs, emerging from a municipal design competition in early 19th century Toulouse that aimed to enhance the city's artistic character. Sculptor Louis-Alexandre Romagnesi contributed his skills to bring this ambitious civic project to life.

The fountain depicts the Three Graces, with winged sirens in bronze resting on a central pillar in the marble basin. Its name comes from the Place de la Trinité where it stands. A near-identical copy, the Fontaine Desprès, was inaugurated in Perpignan on 30 October 1831, following the same model.

The fountain sits on a pedestrian plaza with surrounding cafes and historic shops, making it easy to explore the square from different angles. Visitors can rest nearby or enjoy refreshments while taking time to observe the sculptures and the overall composition.

The same design was reused for the Fontaine Desprès on Place Bardou-Job in Perpignan, inaugurated on 30 October 1831, four years after the Toulouse fountain. The Toulouse fountain has been listed as a monument historique since 1946.
