Basilique St-Martin Tours

In the Middle Ages, Tours was an important pilgrimage city thanks to the relics of soldier-turned-evangelist St Martin (c 317–97). In the 5th century a basilica was constructed above his tomb; in the 13th century it was replaced by an enormous Romanesque church, of which only two towers, Tour Charlemagne and Tour de l’Horloge, remain. Modern-day Basilique St-Martin, a domed, neo-Byzantine structure, was built from 1886 to 1925.
