Even on a tight schedule, Old Jewish Cemetery earns the hours.
Allow 30–45 min.
One of the most affecting and singular sights in Europe — the toppled, overlapping stones rising in waves are unforgettable, and the silence is heavy. The catch: it's only enterable via the pricier Jewish Museum ticket, you follow a roped path past the stones (no wandering), and timed-entry queues bunch up. Brief but profound.
