Ketelhuis

Ketelhuis is a historic brick building located in the city of Delft in the western Netherlands. The structure dates back to the early 17th century, when it originally served as a malt house for the brewing industry that was flourishing in the region. Its name, derived from the Dutch words for “kettle” and “house,” reflects the large copper kettles that were once housed there for the production of barley mash and wort.

Architecturally, Ketelhuis is a prime example of Dutch brick Renaissance style, characterized by a symmetrical façade, horizontal brick patterns, and multi-paned shuttered windows. The building’s original roof was replaced in the 18th century with a steep pitch to better shed rainwater, and a wooden belfry was added in the 19th century, serving both as a fire lookout and a community timepiece.

In the 20th century Ketelhuis fell into disuse, but a restoration project in the 1980s revived the structure. The building was converted into a cultural centre and municipal archive, creating a space that hosts art exhibitions, community events, and archival research. A plaque on the front door commemorates the restoration effort and notes the building's role in Delft’s industrial heritage.

Presently Ketelhuis is managed by the Delft city council and operated by the Stichting Ketelhuis, a non‑profit organization. It remains a popular destination for visitors interested in the city’s colonial trade history, architectural heritage, and local arts scene. The building’s preservation serves as an example of adaptive reuse of industrial heritage in the Dutch urban context.
