Measuring, building and demonstrating left stories in the streets of Paris too. These walks approach scholars, engineers and inventions through places where knowledge took shape. They invite a closer look at instruments, buildings and projects, with curiosity about the people who made them possible and the questions they were trying to answer.
In “The Canal Saint-Martin”: Locks, iron footbridges and swing bridges bring engineering into the uses and transformations of the canal.
In “The Eiffel Tower and the Champ de Mars”: The tower approaches engineering through a project that became one of Paris's best-known images.
In “Cluny, Sorbonne and Saint-Jacques”: Next to it stood the convent where the University buried two hanged students, after forcing the provost to kiss them.

At the Tour Saint-Jacques you'll hear why Nicolas Flamel's tomb was there, how he got his reputation as an immortal alchemist, and what Pascal climbed up to measure.

From the dome of the Panthéon down to the church of Saint-Médard: a sick king's promise, the pendulum that proved the Earth turns, the coffins of Voltaire and Rousseau opened in 1897, a crime inside a church, a penniless Hemingway and three thousand gold coins hidden in a house on the Mouffetard.

Paris works best a neighbourhood at a time. Combine a walk, a pause and another look: the distances on the map can be deceptive.
