3 Things to Look For: (1) Straight ahead: The 215 stained glass windows and 112 gargoyles and statues (including a replica of Darth Vader!) that adorn the National Cathedral; (2)m looking upward: the 30-story central tower, the highest point in DC at 676 feet above sea level; (3) on the ground: the cathedral’s vast North Lawn.
