The Tron Kirk is a former principal parish church in Edinburgh, Scotland. It is a well-known landmark on the Royal Mile. It was built in the 17th century and closed as a church in 1952. Having stood empty for over fifty years, it was used briefly as a tourist information centre and, more recently, has been re-opened as the site of the Edinburgh World Heritage Exhibition and John Kay’s book and gift shop.
The name comes from the weighing beam, serving the public market on the Royal Mile, which stood outside until around 1800.
