Welcome to the heart of the Saint-Étienne district. As you stand here at the crossroad of history, look up at the facade of Toulouse Cathedral. You might notice something immediately striking: it looks like two different buildings were forced together by a giant. This is Cathédrale Saint-Étienne, a structure that has been evolving since at least the ninth century, though much of what you see today was built between the thirteenth and seventeenth centuries. Unlike the perfect symmetry of Notre Dame in Paris, this cathedral is famous for being delightfully lopsided. It is an architectural mystery story written in pink brick and stone, standing as a testament to shifting styles, changing budgets, and the stubborn ambition of the people of Toulouse. Take a deep breath and prepare to step into a space where the rules of geometry were frequently rewritten.
