The Kirk plays an important part in Scottish history. In 1638 the National Covenant was presented and signed in front of the pulpit and in the mid-19th century the first post-Reformation stained glass windows and one of the first organs were introduced into a Presbyterian church in Scotland. Between 1929-38 the historic building was extensively restored and the interior dividing wall between the two former separate sanctuaries was removed. The Peter Collins organ was installed in 1990. www.greyfriarskirk.com
