Schilblokken

Schilblokken (literally "shell blocks") is a Dutch term with multiple regional meanings, and there is no single, widely accepted definition. In construction contexts, the term may be used to describe lightweight or hollow masonry units with a shell-like outer surface. Such blocks are designed to combine structural strength with reduced mass and may feature internal cores or patterned facades that resemble a shell. They are sometimes encountered in modular wall systems or decorative cladding, and can be made from concrete, ceramic, or composite materials.

In geology or paleontology, schilblokken can refer to blocks that contain or preserve shell material, such as fossil shells embedded in sedimentary rock. These blocks may be of interest for study, display, or decorative purposes in museums or building materials. In art or heritage contexts, the term can denote decorative blocks that bear shell motifs or are carved to resemble shells, used in architectural ornament or sculpture.

Because the term is not standardized, its interpretation depends on regional usage and the field involved. If a source or context is provided, a more precise definition can be established. This article may be updated to include that context.
