Florentine tower of Buire, Art Deco tower in Buire, France

The Florentine tower is a signal structure built around 1920 for the Northern Railway and distinguished by its Art Deco facade. This six-story reinforced concrete building combines functional spaces such as storage, workshops, and sanitation facilities with decorative brick elements.

Engineer Raoul Dautry and architect Gustave Umbdenstock designed the building in 1920 as a signal station for the Northern Railway. After the Second World War the structure was taken out of service and has not functioned for railway operations since.

The name "Florentine" is explained in two ways: it may refer to the typical buildings of Florence, or to the Florentine contractor who built the tower of Lens. The Compagnie du Nord built similar towers at Lille la Délivrance, Lens, Béthune, Laon and Aulnoye-Aymeries; most were demolished, but the one at Leval survives and now serves as a social and cultural centre.

The tower stands in Buire, a small town in northern France, and is easily visible from the street. Visitors can view the building from outside, but the interior is not open to the public.

The tower is one of several Florentine towers built by the Compagnie du Nord at stations such as Lille la Délivrance, Lens, Béthune, Laon and Aulnoye-Aymeries. Most were demolished; the Buire tower and the one at Leval, now a social and cultural centre, survive. The name may refer to Florentine building types or to the Florentine contractor of the Lens tower.
