Palais de justice de Douai, 18th-century courthouse in Douai, France.

Palais de justice de Douai is an 18th-century courthouse on Place Charles-de-Pollinchove. Its long red-brick facade faces a canal, with a ground-level colonnade of pointed arches and round brick arches springing from stone capitals. Above are two rows of windows—tall round-arched windows with many small panes below, smaller windows above—under a grey slate roof with dormers and a chimney.

The courthouse is an 18th-century building on Place Charles-de-Pollinchove. The buildings around its first courtyard were listed as monuments historiques by decree on 30 September 1959. A modern extension was built from 1976 to 1978.

The courthouse stands on Place Charles-de-Pollinchove, named after Charles de Pollinchove, a local figure of the 18th century. The brick facade seen from the canal shows pointed arches at its base and round brick arches springing from stone capitals between them, above two rows of windows and a slate roof with dormers.

The courthouse sits on Place Charles-de-Pollinchove in central Douai and is easily reached on foot from the city center. Since it functions as an active judicial building, access may be limited to public areas or restricted during proceedings.

The red-brick facade facing the canal is not the 18th-century building itself: the brick colonnade with pointed arches and the round brick arches on stone capitals belong to the surrounding buildings of the first courtyard, inscribed as monuments historiques on 30 September 1959. The courthouse gained a modern extension built from 1976 to 1978.
