Prior to the arrival of Europeans in the area, Castle Hill was occupied by families of the Kiksadi clan of Tlingits. Alexander Baranov, a leading figure in the Russian-American Company, arrived in the Sitka area in 1795, and sought to establish a trading post on the hill. He ended up establishing Redoubt St. Archangel Michael several miles away in 1799; this trading post was destroyed by the Tlingit in 1802. Baranov returned to Sitka in force in 1804, seized Castle Hill, from which the outnumbered Tlingit had withdrawn. After the six-day Battle of Sitka, the Tlingit formally ceded Castle Hill to the Russians.
