Breadcrumb Visiting the Washington National Cathedral With its neo-Gothic architecture, medieval-style garden and eerie gargoyles, the city’s cathedral is worth a stop whether you’re worshipping or just looking on in wonder. Stained-glass windows, Gothic spires and flying buttresses make the Washington National Cathedral look ages old, but the grand church was actually constructed during the 20th century. Though overseen by the Episcopal Church, the house of worship welcomes people of all faiths to its impressive site on the highest point in DC. History and architecture Stonemasons and builders erected the cathedral beginning in 1907, completing it 83 years later in 1990. Carved from Indiana limestone, the structure boasts a 30-story-tall central tower, an interior nine-bay nave and 215 stained glass windows, including one embedded with a moon rock. Inside, you’ll find a crypt level where Helen Keller and President Woodrow Wilson are buried. On the nave level, you’ll discover an intricately carved wooden choir area and numerous serene chapels.
