The town of Heriz is approximately 40 miles east of the city of Tabriz in north-western Persia. Carpets have     been woven in and around the town of Heriz since the beginning of the nineteenth century. Given its geographical proximity to Tabriz (a historically important centre of Persian rug and carpet production) this has probably encouraged the manufacture in the Heriz area.

Heriz carpets are characteristically geometric in design, usually with a distinctive rectilinear medallion that reaches almost to the borders of the carpet. Reds and browns are the traditional primary colours, with secondary colours typically blue, yellows and creams.

These carpets are amongst the heaviest and most durable Persian carpets that are produced. The weave is unique to Heriz, chunky and robust. Heriz carpets are woven using a double-weft construction (i.e. two wefts between each row of knots), and employing the Turkish (or symmetrical) knot. The pile formed is substantial, and the wool used is of a particularly durable quality. The warps and wefts are distinctively thick and made of cotton. It is unusual for Heriz to make carpets in smaller sizes, but examples do exist. However the weavers of Heriz tend to weave mainly carpet sizes (i.e. 3.50m x 2.50m upwards).
