You’ll want to soak in the sumptuous Baroque interior, admire the pipe organs (maybe playing if you come for a morning service or evensong), and pay homage at the tombs of esteemed Hamburgers in the huge crypt. But save your energy for the climb up the 449 steps of the twisting, narrow staircase (there’s also an elevator for the less adventurous) for a sweeping view of Hamburg from the top of the copper-roofed tower ★.
