Hôtel Bullion

Hôtel Bullion is located at 9 rue du Coq-Héron and displays classical French architecture with carefully detailed stonework on its facades facing both streets. The structure features a protected entrance courtyard and ornamental stone details that reflect its historic importance and former grandeur.

Claude de Bullion, superintendent of finances under Louis XIII, acquired the property in 1613 and architect Salomon de Brosse expanded it in 1614. The redesigned mansion later became a hub for artistic and commercial activity in the capital.

The building functioned as an auction house for art sales until the early 1800s, drawing collectors and enthusiasts to its rooms. Traces of this vibrant market activity remain visible in the structure and layout of the interior spaces.

The building now serves as the headquarters of Caisse d'Epargne bank and can be viewed from the outside, with the protected facade and entrance courtyard being the main points of interest. Note that this is an active banking location, so only the exterior is accessible to visitors.

The structure preserves sections from the original rue Plâtrière layout that survived the extensive urban development of rue du Louvre. This rare continuity of medieval street patterns makes it a valuable window into Paris' building past.
