Whether gazing way out across the harbor islands or over a glittering city nightscape, the views from Fan Pier are inspiring, relaxing and, quite simply, amazing. There are breathtaking vistas that stretch from the Prudential Tower and the Hancock Building to the Zakim Bridge and the iconic spire of the Old North Church. Against this backdrop is Boston Harbor, always in motion, always new, always fascinating. It is a moving tableau, and, when you are not out in the midst of it yourself, it is right outside your windows.
