In the middle of the Royal Mile is the stunning St. Giles’ Cathedral. Built in late 14th century, it has been the principal place of worship of the Church of Scotland in Edinburgh for over 900 years. Mimi and I popped in for a quick visit after leaving Edinburgh Castle and were amazed at the fabulous interior. The cathedral is large, seeped in history and has some really beautiful stone and wood carving throughout. Also found inside are marvelous stained glass windows, which were added to the cathedral in the 19th century. My favorite part of the cathedral was a small side chapel in the rear. It seats only about 50 people, but the ceiling and alter are massively impressive.
