Ita Fort in Itanagar town is an important historical site in the state of Arunachal Pradesh, India.

The Ita Fort at Arunachal Pradesh is generally assumed to be built by the Sutiya kings in the 14th or the 15th century.

The total brickwork is of 16,200 cubic metre lengths which was probably built by kings of the Sutiya kingdom which ruled the region during that time.

Das, in an article published in the Journal of Assam Research Society, claimed the fort to be the capital of Ramachandra/Mayamatta Mayapur.

[7] The Pratapgarh ruins may have formed the eastern borders of the kingdom as evident from the Uma-tumani island (near Biswanath) stone inscription which mentions the ruler as Pratapuradhikari.
