I spent the day exploring more of Edinburgh and enjoying the scenery. First I walked through New Town to a quiet neighborhood where St. Mary's Cathedral is located at Map Location: 55.948536, -3.216437 . This architectural marvel has three massive spires that tower over the city and can be seen from any high point. The interior is not as impressive as St. Giles but entry is free and tourists are welcome. There are bathrooms through the front left exit doors.
The next stop was the historic Greyfriars Kirk (or Kirkyard) and cemetery. Kirk is the Scottish word for church. The cemetery is famous for Greyfriars Bobby a Skye Terrier who guarded his master's grave for fourteen years in the 1800s. The dog is prominently buried in the cemetery and there is also a famous statue of him just outside on the main street. It's customary to rub the statue dog's bronze nose.
The cemetery is also noted for its connection to J.K. Roland who used some of the names from the graves for characters in her Harry Potter books. In the surrounding neighborhood there are several coffeeshops that are considered to be the birthplace of Harry Potter such as the Elephant House and Spoon.
