Begun in the 11th century, Geneva's cathedral is predominantly Gothic with an 18th-century neoclassical facade. Between 1536 and 1564 Protestant John Calvin preached here; see his seat in the north aisle. Inside the cathedral, 77 steps spiral up to the attic – a fascinating glimpse at its architectural construction – from where another 40 lead to the top of the panoramic northern and southern towers .
In summer, free carillon (5pm) and organ (6pm) concerts fill the cathedral and its surrounding square with soul.
