Bidvaz Castle, known locally as Qal'eh-ye Bidvaz, is a historic fortress situated in Esfarayen County within North Khorasan Province, Iran. This ancient structure holds significant archaeological value as its origins trace back to the era of the Parthian Empire, which ruled the region from approximately 247 BC to 224 AD. As a Parthian castle, it represents a tangible link to one of the major political and cultural powers of ancient Iran, serving as a testament to the military and architectural capabilities of that distant period. The site is officially recognized within the national framework of Iranian historical assets, highlighted by its inclusion in records maintained by the Cultural Heritage, Handicrafts and Tourism Organization of Iran.

While specific details regarding its precise construction year, original architects, or distinct architectural style are not extensively documented in available summaries, the castle's classification as a Parthian stronghold defines its primary historical identity. The longevity of the fortress underscores its strategic importance over centuries, likely serving defensive or administrative functions for the communities in the northern Khorasan region. Today, Bidvaz Castle stands as a categorized historical monument, contributing to the rich tapestry of Iran's numerous ancient fortifications. Although current information does not specify its exact state of preservation or modern usage, its enduring presence continues to offer insights into the early history of the province. The site remains an important subject for those studying the evolution of castle architecture and settlement patterns during the Parthian dynasty in northeastern Iran.
