Washington National Cathedral

The 150,000-ton Washington National Cathedral is the second largest cathedral in the U.S. and the sixth largest in the world. The cathedral's collection includes a 7.18-gram basalt rock from the Moon’s Sea of Tranquility brought back to Earth by the crew of Apollo 11, the remains of Woodrow Wilson, the 28th president and only former Commander in Chief to be buried in the District of Columbia, a pulpit from England’s Canterbury Cathedral, a cross made from fragments of the Pentagon after September 11, 2001, and a stone from the Western Wall in Jerusalem. Soaring hundreds of feet above it all are 288 angels, 215 dazzling stained glass windows, 112 gargoyles, and grotesques carved in the likenesses of famous figures including Eleanor Roosevelt, Mother Teresa, Rosa Parks, and Star Wars villain Darth Vader.
