seinämerkein
Seinämerkein is a Finnish term that translates to "wall markings" or "wall signs." It generally refers to any form of inscription, drawing, or symbol applied to a vertical surface, typically a wall. Historically, these markings served a variety of purposes across different cultures. In ancient times, cave paintings and petroglyphs are early examples of wall markings, often depicting scenes of daily life, hunting, or spiritual beliefs. Throughout history, public buildings, religious sites, and even private dwellings have featured wall markings.
In more modern contexts, seinämerkein can encompass graffiti, murals, posters, informational signs, or even decorative elements.
