The Washington National Cathedral is a Christian church that holds Episcopal worship services, and also special prayer services that include political leaders and leaders from all faiths. Family-friendly attractions at the cathedral include stained glass windows, a children's chapel designed to be the size of a 6-year-old child, an organ with 10,600 pipes and gargoyles in the shapes of many different creatures carved into the outside of the structure.
The National Cathedral is a beautiful site in its own right, and walking the Close grounds is a peaceful way to spend a Sunday morning (be sure to check out the Bishop's Garden and the All Hallow's Gift Shop). Families love finding the real moon rock in the huge rose windows and the Girl Scout Trefoil in the stone carvings, but the Cathedral also boasts carvings that appeal more to kids: Star Wars' villain Darth Vader, a fierce bunny, and a unicorn. You can make the visit even cooler for your tween(s) by adding on a tour of the Gargoyles (including Darth Vader!). This tour is a guided tour and the cost is $30/family. As it includes outdoor viewing, the tour is only given during warm weather months, so check out www.nationalcathedral.org/visit in advance to be sure the tour is being offered during your visit.
