The name Dull may be Pictish in origin and derived from the word*dol meaning "water-meadow, haugh".
History
The parish church is on the site of an early Christianmonastery founded by St Adomnán, Abbot of Iona. Several early Christian cross-slabs dating to the 7th or 8th century have been discovered in and around the parish graveyard. A slab carved with stylised warriors and horsemen in the Pictish style, uncovered during grave-digging in the 19th century, is displayed in the Museum of Scotland, and may have formed part of a wall-relief, or one side of a box-shrine. A massive font of rough workmanship, preserved by the church door, is also a probable relic from the early monastic site. The surrounding district was known as the Appin of Dull, the name deriving from Old Irishapdaine referring to the former monastic estate, as with Appin in Argyll, the abbey lands in that case being those of the major early Christian monastery of Lismore. Four undecorated crosses, of which three survive, one at Dull itself, and two in the nearby old church at Weem, once stood around the monastic precinct, defining an area of sanctuary. From the later Middle Ages to modern times, the church at Dull was a parish church in the Diocese of Dunkeld. It is not known when the early Christian monastery ceased to function. In decline for much of the 20th century, with its church and school both going out of use, the small village has seen the construction of several new houses, and the restoration of older buildings, in the 21st century.
Population
In 1951, Dull had a population of 2,055. As of 2012, the population of Dull was approximately 84.
Elizabeth Leighton of Aberfeldy, Scotland, proposed the pairing with Boring, Oregon, while passing through the unincorporated town on the highway from Portland, Oregon, to Mount Hood on a cycling holiday. In June 2012, Boring, Oregon, accepted the proposal to "pair" their municipalities, in an effort to promote tourism in both places as a play on their names. The BoringCommunity Planning Organization issued commemorative "Boring & Dull: a pair for the ages" T-shirts and mugs, raffling off a trip to Dull, Scotland. The Boring CPO will not attempt to get the pairing recognised by the US-based Sister Cities International. Dull and Boring celebrations are held annually on August 9 in Oregon with a piper and a barbershop quartet; the Dull celebrations are in October. Bland Shire, West Wyalong—a farm community and former gold prospecting site in New South Wales, Australia—joined the initiative in 2013, creating not a "twinned town" relationship but a League of Extraordinary Communities to group Dull, Boring and Bland. The group became known as the "Trinity of Tedium".
