Europe's most cobbled Old Towns, measured.

Name: Europe's most cobbled Old Towns, measured

How much of each Old Town's street length is cobbles or setts. Measured street by street from the map, not taken from a guidebook.

The most cobbled is Bruges: 93% of its streets, by length, are cobbles or setts.
19 of 59 Old Towns are at least half cobbled.
Stone is not always cobbles: in Barcelona, 77% of the streets are paving stones and slabs, only 3% cobbles or setts.

How it is measured

Old Town: The same line as on each city's page and in the walking ranking: the historic centre as the city defines it where it publishes a boundary, otherwise the core a visitor walks.
Cobbles & setts: The share of the Old Town's street length whose OpenStreetMap surface is sett (hewn stone blocks, what most people call cobblestones), cobblestone or unhewn_cobblestone.
Paving stones: Smooth pavers and stone slabs, counted apart: modern brick and concrete pavers, but also Venice's trachyte and Santiago's granite flags. Stone underfoot, not cobbles, so they stay out of the first column.
Surface mapped: How much of the street length has any specific surface in OpenStreetMap. A street nobody has tagged counts as not cobbled, so every number is a floor: the real share can be higher, by at most the unmapped rest. An Old Town is ranked only when at least 85% is mapped.
Not ranked: Old Towns where less than 85% of the street length has a mapped surface, so any number would be a guess: Dubrovnik (65%), Palma (83%).
Using the numbers: Quote them freely. A link to this page or to the city's own page is all I ask. Map data © OpenStreetMap contributors (ODbL).
