Anglo-Persian War. In 1857 hostilities between the Persians and the British ended after the Treaty of Paris was signed, and the Persian troops withdrew from Herat. Afghanistan reconquered Herat in 1863 under Dost Muhammad Khan, two weeks before his death. Khorasan was the largest province of Iran until it was divided into three provinces on 29 September 2004. The provinces approved by the parliament of Iran (on 18 May 2004) and the Council of Guardians (on 29 May 2004) were Khorasan-e Razavi, North Khorasan, and South Khorasan. Archaeological sites Among the archeological sites discovered in this province: Kohandezh hills Excavations conducted by an American team between 1935 and 1940 in Nishapur discovered museum-worthy objects, which were shared with the government of the Shah. The Metropolitan Museum of Art's publications document its own Nishapur ceramics from those excavations. For half a century after 1945 the site of Nishapur was ransacked to feed the international market demand for early Islamic works of art. Nowadays, the Kohandezh hills reveal the remains from those excavations. Shadiyakh Shadiyakh was an important palace in old Nishapur up to the 7th century, and became more important and populated after that. The palace was completely ruined in the 13th century. It was the home of notables such as Farid al-Din Attar, whose tomb is found in Shadiyakh.
