Walking Tour of Peaceful Places in Amsterdam's Southern Historic Centrum

Turn left onto Grimburgwal to round the corner of the House on the Three Canals; then head to the far (odd) side of Oudezijds Actherburgwal (one of my favorite small canals of Amsterdam). Look for the gray stone passageway almost immediately on the right. This 18th-century pass-through is now home to a used book market.
