The Book of Kells is an illuminated manuscript Gospel book in Latin, containing the four Gospels of the New Testament together with various prefatory texts and tables. It was created in a Columban monastery in either Scotland, England or Ireland and may have had contributions from various Columban institutions from each of these areas. It is believed to have been created c. 800 AD. The text of the Gospels is largely drawn from the Vulgate, although it also includes several passages drawn from the earlier versions of the Bible known as the Vetus Latina. It is a masterwork of Western calligraphy and represents the pinnacle of Insular illumination. It is also widely regarded as one of Ireland's finest national treasures. The manuscript takes its name from the Abbey of Kells, which was its home for centuries.

The Dupplin Cross is a carved, monumental Pictish stone, which dates from around 800 AD. It was first recorded by Thomas Pennant in 1769, on a hillside in Strathearn, a little to the north Forteviot and Dunning.

The House of Óengus is a proposed dynasty that may have ruled as Kings of the Picts, as well as overlords of the Kings of Dál Riata and possibly of all of northern Great Britain, for approximately a century from the 730s to the 830s AD. Their first ruler of Pictland was the great Óengus I of the Picts, who may be the figure carved into the St Andrews Sarcophagus pictured on the right.

The Kingdom of the Isles consisted of the Isle of Man, the Hebrides and the islands of the Firth of Clyde from the 9th to the 13th centuries AD. The islands were known to the Norse as the Suðreyjar, or "Southern Isles" as distinct from the Norðreyjar or Northern Isles of Orkney and Shetland. In Scottish Gaelic, the kingdom is known as Rìoghachd nan Eilean. The historical record is incomplete, and the kingdom was not a continuous entity throughout the entire period. The islands concerned are sometimes referred to as the Kingdom of Mann and the Isles, although only some of the later rulers claimed that title. At times the rulers were independent of external control, although for much of the period they had overlords in Norway, Ireland, England, Scotland or Orkney. At times there also appear to have been competing claims for all or parts of the territory. The islands involved have a total land area of over 8,300 square kilometres (3,205 sq mi) and extend for more than 500 kilometres (310 mi) from north to south.
The Kirriemuir Sculptured Stones are a series of Class II and III Pictish stones found in Kirriemuir, Angus, Scotland. Their existence points to Kirriemuir being an important ecclesiastical centre in the late first millennium AD.

The Scar boat burial is a Viking boat burial near the village of Scar, on Sanday, in Orkney, Scotland. The burial, which dates to between 875 and 950 AD, contained the remains of a man, an elderly woman, and a child, along with numerous grave goods. Although the site had to be excavated quickly because of the threat of coastal erosion owing to bad weather conditions, it yielded many important finds.

The Siege of Dumbarton was a successful four-month siege of the Brittonic fortress at Dumbarton Rock in 870, initiated by the Viking leaders Amlaíb, King of Dublin, and Ímar. Dumbarton was capital of the Kingdom of Alt Clut, the only surviving Brittonic kingdom outside of Wales. It represented a valuable target for the Viking invaders, who were likely motivated by strategic considerations, as well as loot. The attackers may have wished to remove Alt Clut as a maritime power, and the location and defensiveness of Dumbarton itself was of major value.
