In geometry, the circumference is the perimeter of a circle or ellipse. The circumference is the arc length of the circle, as if it were opened up and straightened out to a line segment. More generally, the perimeter is the curve length around any closed figure. Circumference may also refer to the circle itself, that is, the locus corresponding to the edge of a disk. The circumference of a sphere is the circumference, or length, of any one of its great circles.

Long Meg and Her Daughters is a Neolithic stone circle situated north-east of Penrith near Little Salkeld in Cumbria, North West England. One of around 1,300 stone circles in the British Isles and Brittany, it was constructed as a part of a megalithic tradition that emerged during Neolithic, and continued into the Early Bronze Age. The stone circle is the third widest in England, behind Avebury in Wiltshire, and only slightly smaller than Stanton Drew in Somerset, consisting of 59 stones set in an east/west oval configuration measuring 340 ft on its long axis. There may originally have been as many as 70 stones. Long Meg herself is a 12 ft high monolith of red sandstone 80 ft to the southwest of the circle made by her Daughters. Long Meg is marked with examples of megalithic art including a cup and ring mark, a spiral, and rings of concentric circles.
The Sator Square is a two-dimensional acrostic class of word square containing a five-word Latin palindrome. The earliest squares were found at Roman-era sites, all in ROTAS-form, with the earliest discovery at Pompeii. The earliest square with Christian-associated imagery dates from the sixth century. By the Middle Ages, Sator squares had been found across Europe, Asia Minor, and North Africa. In 2022, the Encyclopedia Britannica called it "the most familiar lettered square in the Western world".

The Roman Rota, formally the Apostolic Tribunal of the Roman Rota, and anciently the Apostolic Court of Audience, is the highest appellate tribunal of the Catholic Church, with respect to both Latin Church members and the Eastern Catholic members and is the highest ecclesiastical court constituted by the Holy See related to judicial trials conducted in the Catholic Church. An appeal may be had to the pope himself, who is the supreme ecclesiastical judge. The Catholic Church has a complete legal system, which is the oldest in the West still in use. The court is named Rota (wheel) because the judges, called auditors, originally met in a round room to hear cases. The Rota was established in the 13th century.

In geometry, a Steiner chain is a set of n circles, all of which are tangent to two given non-intersecting circles, where n is finite and each circle in the chain is tangent to the previous and next circles in the chain. In the usual closed Steiner chains, the first and last circles are also tangent to each other; by contrast, in open Steiner chains, they need not be. The given circles α and β do not intersect, but otherwise are unconstrained; the smaller circle may lie completely inside or outside of the larger circle. In these cases, the centers of Steiner-chain circles lie on an ellipse or a hyperbola, respectively.
In geometry, two or more objects are said to be concentric when they share the same center. Any pair of objects with well-defined centers can be concentric, including circles, spheres, regular polygons, regular polyhedra, parallelograms, cones, conic sections, and quadrics.
