St. Ursula is allegedly perched atop the ancient Roman graveyard where the martyred virgins associated with the saint are buried. Though the nave and crossing tower are Romanesque (like St. Martin), the choir was rebuilt in a Gothic style like the Dom. Famously, the interior houses the 17th-century Golden Chamber, where the bones found in the gravesite are arranged in whimsical patterns and even spell out Latin words.
