The Basilica of Saint-Martin d'Ainay (French: Basilique Saint-Martin d'Ainay) is a Romanesque church in Ainay in the Presqu'île district in the historic centre of Lyon, France. A quintessential example of Romanesque architecture, it was inscribed on the UNESCO World Heritage List along with other notable buildings in the centre of Lyon as a testimony to Lyon's long history as an important European town and unique blend of architectural styles.[1]
