Washington National Cathedral

The English-style, neo-Gothic National Cathedral is purported to be the sixth largest cathedral in the world. It took 83 years to build, from 1907 to 1990. Even today, the work on the stone carvings and the stained-glass windows is ongoing.

The original design was created by George Federick Bodley and Henry Vaughn but when they died within 10 years of the first stone being laid, it was later modified by Boston architect Philip Hubert Frohman.

The top of its central tower is one of the highest points in Washington. It is the burial site of President Woodrow Wilson and Helen Keller. The Cathedral is part of the Episcopal Church but holds many interdenominational events and services.
