The red number the descriptive number (číslo popisné) is a unique identifier for each building within a cadastral area. Think of it as the building’s official ID its permanent address within the district. It’s a number assigned way back in 1770 under Empress Maria Theresa a result of soldiers going door to door counting homes. That’s why lower numbers often indicate older buildings.
The blue number however the orientational number (číslo orientační) tells a different story. Introduced later in the 19th century this number serves for navigation. It sequences houses along a street or square making it easier to locate specific addresses. The numbers follow a typical pattern odd on one side even on the other.
The double numbering system isn’t just about finding places. It reflects Prague’s history its evolution from a collection of independent towns to a unified city.
