As you wander through the labyrinthine cobblestone alleys of Prague’s Old Town and Malá Strana, look upward. Before street addresses became the standard, the city relied on a charming, visual language to navigate its winding paths. Today, these historical Prague house signs remain as silent storytellers, carved into gables, painted on facades, and swinging above the doorways of the city’s most storied establishments.
The Origins of Prague House Signs
Dating back to medieval times, the system of house signs was essential for a population where literacy was not universal. These symbols served as landmarks, helping locals and travelers find their way to pubs, hotels, and workshops. While some signs were purely decorative, many were carefully chosen to advertise the trade conducted within, such as U zeleného hroznu (The Green Bunch of Grapes), which still marks a traditional wine shop in the Lesser Town.
Other signs, like U železných dveří (The Iron Door), were named after unique architectural features that have often long since vanished. You will also notice a frequent use of the word zlatý (gold) throughout the city. This trend reflects Prague’s enduring nickname, “Golden Prague,” which pays homage to either the shimmering copper roofs of the Charles IV era or the mystical legacy of the alchemists who worked under the patronage of Rudolf II.
Deciphering the Dual Numbering System
In the 1770s, the Habsburg monarchy introduced a formal registration system to categorize every building in the city chronologically. However, as the city expanded, a more logical, progressive street-numbering system was eventually implemented. This transition left a unique historical footprint that you can still spot on many buildings today.
Understanding the Red and Blue Plates
If you look closely at the entrance of historic pubs like U medvídků (The Little Bears), you will often see two distinct numbers displayed side-by-side. These plates are a fascinating guide to the city’s administrative history:
- The Red Plate: This is the original Habsburg-era house number, representing the building’s place in the city’s historical registry.
- The Blue Plate: This is the modern, orientation-based number used by postal services and emergency responders today.
