Another beautiful spot: The Liston
Some people say that the Liston is named after "The List" -- a register of nobility who were allowed to walk along the arcade. It's also called Platia and The Esplanade.
The arcade looks very much like the Rue de Rivoli in Paris, which is no coincidence. The Liston was built during the short French occupation of Corfu, about the same time as the facade of the Rue de Rivoli was built.
I've read that the Liston was built by the same architects. But the arcade in Corfu was built in 1807 by a French engineer, Mathieu de Lesseps, while the Rivoli's uniform arcade was imposed by the master plan of Napoleon's official architects, Fontaine and Percier.
I suppose de Lesseps may have worked on the Rivoli project and then scurried to Corfu -- but I would guess that both projects reflected the French fashion of the time.
