added by archaeologs In the later 5th century a group of Gaelic-speaking people known as the Scotti travelled from western Ireland to the northeast coast of Scotland (modem Argyllshire). There they founded the kingdom of Dalriada, which was imposed upon a native Pictish population. The Dalriada introduced the Picts to their version of the ogham script as well as the Scottish/Gaelic language. There are secure place-name and linguistic links between this part of Scotland and Ireland, and the history and royal successions of Dalriada are recorded in The Chronicle of Dalriada and elsewhere. However, there is little archaeology to illuminate this migration. The one site of real importance is Dunadd in Crianan Moss, a nucleated fortified citadel dating to around 500 and thought to be the capital of It consists of a dry-stone central stronghold with two outer walled enclosures, and was extensively excavated in 1929.
