A curb is a type of ornamental brickwork in which a row of bricks is laid at an angle to the wall surface (edge out) [1] . It was used by ancient Russian architects, in particular, it was popular in Veliky Novgorod and Pskov .
Due to the ease of execution, this motif was actively used to decorate temples from the 15th to the end of the 19th century. In 20th century architecture, curbs can be found in buildings that inherit the “Russian style”.
The curb should be distinguished from the runner , with whom he was often used. The relief ledges of the brick grew out of the wall at an angle of 45 °, and a runner's Christmas tree curled next to such a “toothed” strip. Old Russian architects appreciated this pattern of ordinary brick or slab, encircling them with the drums of domes and semicircles of apse. Monochrome “braid” of three stripes of decor has become the hallmark of Pskov masters. Local churches were decorated according to the ornamental pattern "curb - runner - curb." Unlike other types of decor, the curb does not overlap the wall plane, but grows out of it.
