The Persian Heriz rugs belong to a family of regional Persian rugs. These rugs were produced in the Iranian province of Eastern Azerbaijan and the area surrounding Heriz.

The village of Serab (or Sarab), where Serapi rugs are generally attributed to, is located south of the region responsible for the eponymous Heriz rugs – the region of North West Persia – and less than 80 miles east of Tabriz. The term Serapi is often applied to the finest antique rug examples from the Heriz area. However, the Serapi designation is a hot topic that is contested by many experts. Nevertheless, Serapi rugs particularly those produced prior to the turn of the 20th century are in high demand today.
Antique Serapi rugs were made by small workshops and families, which resulted in formal Persian carpets as well as those with rustic tribal influences. Local production methods contributed to the characteristic abrash that adds a textural appearance to the stark field and contrasting decorations seen in many Persian Serapi rugs. These fine antique carpets were made in many sizes and shapes ranging from elongated corridor carpets to highly desirable room-size rugs. Persian Serapi rugs feature clear colors, creamy un-dyed fleece beautifully tempered reds, warm earth tones and concentrated blues.
