- The fourth season of excavation in the
Tabaran ancient fortress located near Tus in the
northeastern Iranian province of Khorasan was completed
in the wake of discovering the main entrance of the
fortress, a turning point in the history of excavations
in this site.
Aiming at finding answers to the previous questions
remaining unanswered during the previous phases of the
excavation works in this historical site, the fourth
season had started in the late June.

always been one of the perplexing puzzles about this
ancient fortress which has finally been solved by its
discovery”, said Saberi, the head of the excavation

He went on to say that the main entrance of the ancient
fortress discovered in the fourth season has two towers
on the two sides and a platform-like area in front of
the entrance where a cantilever bridge likely existed,
given the existence of a trench in the back.
In the previous seasons of excavation conducted in the
Tus fortress, a government citadel and a wide round
shaped area have been found where it seems to have been
the prison of the citadel.
The Tabaran ancient fortress used to be the main
resident of the governor of Tus in the Samanids era up
