The Caravanserai of Aruch is located near the village by the same name, in the region of Astarak, in the Republic of Armenia (approx. coord. 40-19/ 44-08). From the 1700's until 1970 the village was referred to as Talish. Only the northeast section of the structure is still standing and has not been studied in any great detail. There is no documentary information available as to the date of its construction, but on the evidence of its architectural detailing it has been attributed to the 13th century.

The caravanserai, which was partially restored in 1957, was originally a rectangular structure with elongated east / west walls. The interior was divided into a long central hall with two narrower side aisles by a series of free-standing pillars. On the exterior of the east elevation are preserved the remains of two semi-circular towers. These towers gave the structure a fortress-like appearance. The portal was probably located in the middle of the south facade, and on the basis of its structural evidence, the entire building was barrel-vaulted and covered by a gabled roof.
