Saint-Germain-des-Prés keeps the oldest church tower still standing in Paris, finished around the year 1000, and inside, the nave is painted blue and gold from floor to vault. Gold stars cross the deep blue vaults and the columns are painted red and green. Twenty large scenes run in pairs along the nave walls, the Old Testament on one side and the New on the other. Most visitors expect bare stone inside an old church, but that bare look is itself a later fashion.
This blue and gold interior is far newer than the church carrying it: nineteenth-century work, two painters, twenty-one years, and a full cleaning in our own time. The abbey behind it is much older. A Frankish king founded it in meadows outside the city, and prés is still French for meadows. Later it passed to Benedictine scholars who made themselves useful in an unexpected way — they worked out how to tell a genuine medieval charter from a forgery. The Revolution shut them out. Go outside and look at the choir end: two more towers once stood there, and they were cut down to stumps.
