Paris

Despite being one of the largest and most famous cities in the world, Paris is rarely mentioned as a part of the wizarding world, though presumably it is as significant for French wizards as London is for their British counterparts. We do know, however, that Gladrags Wizardwear has a location in Paris (along with London and Hogsmeade) (GF8).

The real-life Nicolas Flamel also lived in Paris – and in an early, handwritten version of PS, Rowling mentioned that Flamel was spotted at the opera in Paris in 1762 – though this line never made it into the final book (JKR).
