A high cross is a freestanding stone cross often decorated with carvings. In Ireland and Britain, people made large stone crosses during the early medieval period. These may have started from wooden crosses with metal parts or older stone memorials. The Pictish stones in Scotland might have influenced their design. The earliest known examples are from Northumbria, where Irish missionaries brought Christianity. It is not clear if the cross design began in Ireland or Britain.
The carvings on the crosses mix religious images with patterns like knots and twisted designs. In Britain, vine-scrolls are also used. These styles appear in other artworks like books and metal items. The crosses were likely painted, maybe over a plaster layer. Over time, the paint has worn off, and weathering has made some carvings hard to see, especially scenes with many small figures.
Early crosses were about 2 meters (6.5 feet) tall. Later, in Ireland, some reached up to 6 meters (20 feet), like the Tall Cross at Monasterboice, which is 7 meters (22 feet) tall. Anglo-Saxon crosses were usually slimmer but could be large. Their decoration is mostly ornamental, not showing figures. The Celtic cross, with a ring around the intersection, may have started at Iona. An example from a 5th–7th century Coptic textile shows this style earlier. The term "high cross" is mainly used in Ireland and Scotland, but the tradition is similar across Britain and Ireland, with regional differences.
Some crosses were placed near churches or monasteries, while others marked boundaries or crossroads. It is unclear if they were used for preaching early on. Many have been moved from their original spots. They were not used as grave markers in the early medieval period. In the 19th century, Celtic Revival crosses, with insular-style decoration, became popular as gravestones and memorials. These are now found worldwide, but unlike original Irish crosses, they usually do not have figures.
Ireland and Great Britain
High crosses are the most important remaining examples of Insular art. The largest number in Britain survive from areas where Celtic Christianity lasted until later times. No wooden or metal crosses from earlier times have survived. The designs on early crosses likely borrowed from metalwork, similar to how Insular illuminated manuscripts used similar styles. Saint Adomnán, who was an abbot of Iona and died in 704, wrote about wooden crosses with rings that were later replaced by stone versions. The earliest surviving stone crosses may be the Carndonagh stones in Donegal, Ireland, which were likely built by missionaries from Iona fleeing Viking attacks. These crosses helped spread the design of ringed crosses. The round shapes on early crosses may have come from Pictish stones. High crosses may date back to the 7th century in Northumbria, which included parts of southeast Scotland and Ireland, though some Irish dates are now thought to be later. Most well-preserved early crosses, such as those at Ruthwell, Bewcastle, Iona, and the Kildalton Cross, were likely made around or slightly before 800 AD, even though Northumbrian and Celtic styles differ. Over time, high crosses spread to other parts of the British Isles, including Wales, Devon, Brittany, and Cornwall, where ogham inscriptions show Irish influence. Some examples also appear in Europe, where Insular missionaries carried the style.
Most Irish high crosses have the ringed Celtic cross shape and are larger and more decorated than those in other regions. Many Irish crosses have survived better than those in Britain, where most crosses were destroyed or damaged after the Reformation, leaving only parts of the shaft. The ring on the cross helped strengthen the structure but also became a decorative feature.
High crosses were symbols of status for monasteries, sponsors, or patrons and may have been used for teaching. Some crosses include inscriptions naming the person who built them, like Muiredach's High Cross and the Bewcastle Cross. Early 8th- or 9th-century Irish crosses had only decorative patterns, such as interlace and round shapes. By the 9th and 10th centuries, images of figures appeared, including Christ on the cross. The largest 10th-century examples have many figures across the surface. A notable example is the Ardboe Cross in Ireland, which is about 18 feet tall and has 22 panels showing biblical scenes. Later Irish crosses sometimes show fewer figures, like Christ with a local bishop or abbot, carved in very detailed relief. The Irish tradition of high crosses declined after the 12th century but was revived in the 19th century during the Celtic Revival. These crosses are now used worldwide for memorials and gravestones, often with only decorative patterns and inscriptions.
Anglo-Saxon crosses were usually slimmer and square-shaped, but those near Celtic areas, like the Ruthwell and Bewcastle crosses, were larger to match local expectations. The two 9th-century Sandbach crosses in England are the largest of their time. The heads of these crosses were smaller and not always ringed, though many have not survived. Carved figures on large Anglo-Saxon crosses were larger and more detailed than those on similar Irish crosses. Anglo-Saxon designs often combined vine-leaf patterns with interlace, similar to Celtic styles. Smaller crosses may have only had decoration and inscriptions, which were more common on Anglo-Saxon than Irish crosses.
After Viking invasions, Norse settlers in the Danelaw adopted the cross design, blending Christian and Norse symbols. The Gosforth Cross in England is a rare example of this mix. By the 10th century, these Anglo-Norse crosses were common in England, while high crosses were no longer made further south. Simple Dartmoor crosses, made of tough granite, were used for centuries to help travelers navigate the area. These crosses have minimal decoration and are hard to date. Market crosses, many from the medieval period, have been built and replaced until modern times.
In Pictish Scotland, cross-slabs developed as a mix of Pictish stones and high crosses. These were flat stones with a cross carved on one side and decorated with interlace or other patterns on the rest. They are different from true high crosses.
Scandinavia
The tradition of building high crosses began when Norse settlers arrived in the British Isles and encountered a Christian culture. A partially broken cross found in Granhammar, Vintrosa parish, Närke, Sweden, shows evidence of an English mission in central Sweden. This Swedish cross was very similar to one in Leek, Staffordshire, and may have been created by an English person who moved to Sweden. In Norway, the British tradition of high crosses was more widely accepted, with about 60 stone crosses known in the country. However, only four of these can be clearly linked to the Viking Age because they have runic inscriptions. Many of the crosses were likely placed on pagan burial grounds when families converted to Christianity. Later, they were moved to cemeteries. The high cross tradition may also have influenced the popularity of raising runestones (often with carved crosses) in Sweden.
Modern period
From the 19th century, many large modern versions of Celtic crosses have been built for different purposes. Smaller Celtic crosses are now often used as markers for individual graves, usually decorated with simple, abstract patterns like twisted designs.
In 1887, the Rev. William Slater Calverley asked for a full-sized copy of the Gosforth Cross to be made and placed in the churchyard at Aspatria, Cumbria.
In the early 21st century, Irish sculptor Brendan McGloin was asked by the Ancient Order of Hibernians in Portland to create a full-sized replica of the Clonmacnoise Cross of the Scriptures. The 13-foot, 5-tonne sandstone cross was finished in 2007 and sent from Donegal to Portland, Oregon, where it now stands as a Famine memorial. In 2016, a high cross was built outside Wakefield Cathedral in West Yorkshire, England. It was made from stone taken from Holmfirth and carved by Celia Kilner. This cross was modeled after the remains of a Saxon high cross from around 930 A.D.
