Boot scraper

A boot-scraper,[1] door scraper,[2] mud scraper, or decrottoir is a device consisting of a metal blade, simple or elaborate, permanently attached to the wall or to the sidewalk at the entrance to a building to allow visitors to scrape snow, mud, leaves, or manure off the soles of their footwear before entering.

The simplest shoe scrapers could be a rectangular sheet of metal, a horizontal bar, or thick steel wire, but many had more complex shapes made of cast iron or wrought iron with horizontal center piece to scrape off the sole, vertical scraping surfaces to clean the sides of the boot, and other shapes to access concave area by the heel.

On building entrances, boot scrapers could be cemented into the pavement, protrude from a house walls, hide in a niche built into the facade, or sometimes integrated into wrought-iron banisters.

[3] Originally placed directly on foot paths, some were banned as a danger to public safety and placed in niches in the facades.

[4] Through the 20th century, the scrapers of European cities fell into disuse and many were removed during roadworks, or salvaged for ferrous metals.
