Tribunal de commerce de Paris

The Tribunal de commerce de Paris is a courthouse on Île de la Cité with a rectangular footprint of 50 by 70 meters topped by a distinctive octagonal dome. This dome rises approximately 45 meters above the northern riverbank and crowns a seven-story structure that houses all commercial justice functions in one place.

Construction of the current building began in 1859 after being commissioned by Napoleon III, with architect Antoine-Nicolas Bailly overseeing the design and execution. The project reached completion in 1865, consolidating commercial justice functions that had been scattered across various Paris locations into a single powerful institution.

The main entrance displays statues representing law, justice, firmness, and prudence that visitors see upon arrival. Busts of notable French historical figures line the interior spaces, making the building itself a gallery of figures important to the nation's legal tradition.

The building sits on the northern bank of Île de la Cité and is recognizable by its prominent dome from various vantage points around the island. Since this is an active courthouse, visitors should expect that access to interior spaces may be limited and advance arrangements might be necessary for viewing.

The dome design was inspired by Brescia City Hall in Italy, blending Renaissance architectural elements with French Second Empire style. This cross-European influence reflects how 19th century French architects drew from diverse traditions to create something distinctly new.
