Ruined bridge (Sassanian or medieval Islamic?), of which only the southern arch remains. Discussed in A. Stein (1940).
Sassanian and early medieval Islamic zoorastrian Fire Temple complex, consisting of a southern chahārtāq and an excavated northern squared building.
Probable archaeological site. Round site on a natural riverine terrasse, visite on 2002 satellite imagery, since destroyed. Possibly associated with Kheirabad fire temple complex.
