#RanikotFort (Sindhi: رني ڪوٽ‎) is a historical fort near Sann, Jamshoro District, #Sindh, Pakistan. Ranikot Fort is also known as The Great Wall of Sindh and is believed to be the world’s largest fort with a circumference of approximately 26 kilometres (16 mi). Since 1993, it has been on the tentative list of @UNESCO World Heritage Sites. The original purpose and architects of Ranikot Fort are unknown. Some archaeologists attribute it to Arabs, or possibly built by a Persian noble under the Abbasids by Imran Bin Musa Barmaki who was the Governor of Sindh in 836. Others have suggested a much earlier period of construction attributing to at times the Sassanians Persians and at times to the Greeks. Despite the fact that a prehistoric site owf Amri is nearby, there is no trace of any old city inside the fort and the present structure has little evidence of prehistoric origins. #MehwishAbbasi
