Original Style Victorian Inverlochy PatternThis pattern takes its name from the design on the original floor at Inverlochy Castle, a grand Victorian house in Scotland. Shown with a Byron border. Geometrically speaking, an octagon (derived from the Greek for eight angles) is a polygon that has eight sides. The shape has been in use in architecture for many centuries, especially for religious buildings. The number eight is considered lucky in many cultures, especially in China and Japan.
