The design consists of circles, arcs and lines. As its name says, it is round and consists of a ring drawn with interlaced circles, and in the central part of the ring there is another simple design. Since it has been drawn with precision, the design is suitable to be copied and used for some other graphic projects. Due to the title of the book in which this decorative element was found, we called it ‘architectural’ but, to be true, it is a simple round interlaced design that can be used in a number of ways.
