The houses in the La Petite France area adopt a unique architectural style known as Fachwerk. This style features timber-framed buildings, where the wooden frame is filled with materials like mud or bricks.
The outer walls are painted in light pastel tones, giving the buildings their distinct aesthetic, with an overall atmosphere reminiscent of the Medieval and Renaissance periods.
The Fachwerk architecture in this region is adapted to the climate of Alsace, which is humid and has heavy snowfall during winter. As a result, the buildings are characterized by steep, sloped roofs. These roofs also provide additional living space in the form of attics.
The Fachwerk structure is made by filling a timber frame with mud or bricks. These materials were easily available from the surrounding forests, making this architectural style a practical choice for the region.
