Definition
Treillage refers to an architectural framework of light wooden or metal bars, often arranged in a lattice pattern. It's like a fancy trellis, but often more decorative and integrated into the architecture of a building or garden. Think of it as ornamental latticework designed to support climbing plants or simply add visual interest. It's frequently used in formal gardens and courtyards. Unlike a simple trellis, treillage is often painted and designed to be a permanent feature. It gives a sense of depth and enclosure to outdoor spaces.
