If you look at Cologne’s coat of arms, you’ll see what looks like 11 apostrophes. In fact, it represents the Christian martyrs St Ursula and 10 virgins. The church of St Ursula stands atop the Roman graveyard where the virgins’ remains were allegedly found. In the 17th century, the richly ornamented baroque Goldene Kammer (Golden Treasury) was built to house their relics.
