Declaration of Arbroath. Campaigners believe that the Abbey's historical pronouncement makes it a prime candidate to achieve World Heritage Status. MSP Alex Johnstone wrote "Clearly, the Declaration of Arbroath is a literary work of outstanding universal significance by any stretch of the imagination" In 2008, the Campaign Group Chairman, Councillor Jim Millar launched a public petition to reinforce the bid explaining "We're simply asking people to, local people especially, to sign up to the campaign to have the Declaration of Arbroath and Arbroath Abbey recognised by the United Nations. Essentially we need local people to sign up to this campaign simply because the United Nations demand it." Architectural description The Abbey was built over some sixty years using local red sandstone, but gives the impression of a single coherent, mainly 'Early English' architectural design, though the round-arched processional doorway in the western front looks back to late Norman or transitional work. The triforium (open arcade) above the door is unique in Scottish medieval architecture. It is flanked by twin towers decorated with blind arcading. The cruciform church measured long by wide. What remains of it today are the sacristy, added by Abbot Paniter in the 15th century, the southern transept, which features Scotland's largest lancet windows, part of the choir and presbytery, the southern half of the nave, parts of the western towers and the western doorway. The church originally had a central tower and (probably) a spire. These would once have been visible from many miles over the surrounding countryside, and no doubt once acted as a sea mark for ships. The soft sandstone of the walls was originally protected by plaster internally and render externally. These coatings are long gone and much of the architectural detail is sadly eroded, though detached fragments found in the ruins during consolidation give an impression of the original refined, rather austere, architectural effect. The distinctive round window high in the south transept was originally lit up at night as a beacon for mariners. It is known locally as the 'Round O', and from this tradition inhabitants of Arbroath are colloquially known as 'Reid Lichties' (Scots reid = red). Little remains of the claustral buildings of the Abbey except for the impressive gatehouse, which stretches between the south-west corner of the church and a defensive tower on the High Street, and the still complete Abbot's House, a building of the 13th, 15th and
