Hôtel de Coislin, Private mansion at Place de la Concorde, Paris, France
The Hôtel de Coislin is a private mansion located at the corner of Rue Royale and Place de la Concorde in Paris's 8th arrondissement. Its facade features a portico with four columns that support an entablature topped by a classical pediment.
The mansion was built in 1770 by architect Ange-Jacques Gabriel for Marie-Anne de Mailly-Rubempré. It became historically significant when key French-American diplomatic agreements were signed within its walls in 1778.
The mansion served as a gathering place for Parisian high society and became known for hosting refined social events. Artists documented life within its walls, making it a symbol of elite culture during the 1800s.
The building sits at a prominent location on Place de la Concorde, making it easy to find and view from the surrounding public spaces. Since it is a private residence, visitors should expect to observe the architecture and details from the street level rather than entering the interior.
A precise architectural replica of this mansion exists in Philadelphia, built by American architect Horace Trumbauer using the original French design. This rare example of transatlantic architectural replication remains largely unknown to most visitors.
