Zibad Castle
Zibad Castle is one of the four historical monuments of Zibad. It is located in Gonabad and is believed to be the last shelter of the last Sasanian emperor Yazdegerd III. It was registered in 2001 as a national heritage property in Iran, as it is related to the history of pre-Islamic Iran. In addition to the castle of Zibad, there is also the royal castle of Zibad, nationally registered under the name of Shahab Castle in 2002. Sources conflict as to the exact manner of the emperor's final moments. One suggests that after his defeat, he sought refuge at a millers near Marv, who killed Yazdegerd in order to obtain his jewelry, whilst the Cambridge History of Iran states that the miller was sent by Mahoe Suri. According to the history of Belazari, Yazdegerd III was defeated in a war in the city of Gonabad. According to the excavations of Zibd-Gonabad Fortress and according to oral narrations and the report of Blazeri and Habib Abdolhai,Dr Ajam and Abas Zmani (historical study magazine 1974),  it seems that the narration related to the murder of Yazdgerd in Merw Mill is more mythical than the truth. What is closer to the truth is the narration of Al-Baladhuri in Kitab Futuh al-Buldan, that he was killed in Gonabad

The main text of Blazeri's book The Fate of Yazdgerd III:

Then he went to Khorasan, then he went to Janabad (Gonabad) he was welcomed and ruler of merv send Nizak Trkhan to welcom him in gonabad. but after weeks he asked the emperor to marry his daughter and the emperor  refused and this caused a war and at the end Nizak attacked and defeated the king army and Destroyed and captured the remnants of the imperial forces. the battle was occurred in Zibad gonabad. Mahoe Suri was probably from the House of Suren, one of the seven Parthian clans of the Sasanian state. During the Islamic invasion of Iran, Yazdegerd III went to refuge in Marv; in his way to merv he stayed in gonabad  Mahoe envoy warmly received them in gonabad. Mahoe Suri used opportunity to secretly plot with the Hephthalite ruler Nizak against Yazdegerd. Regardless, the death of Yazdegerd marked the end of the Sasanian Empire, and made it less difficult for the Arabs to conquer the rest of Iran. All of Khorasan was soon conquered by the Arabs, who would use it as a base to attack Transoxiana. The death of Yazdegerd thus marked the end of the last pre-Islamic Iranian empire after more than 400 years of rule. An empire–which had a generation earlier briefly conquered Egypt and Asia Minor, even reaching as a far as Constantinople, fell to a force of lightly equipped Arabs that were used to skirmishes and desert warfare. The heavy Sasanian cavalry was too sluggish and systematized to contain them; employed light-armed Arab or East Iranian mercenaries from Khorasan and Transoxiana would have been much more successful.
