Commonly referred to as Castle Hill, this park is one of the most historically significant sites in Alaska. Tlingit natives originally inhabited this area and built a strategic fortification at this site. 

 In 1867, on top of Castle Hill, Alaska was officially transferred from Russia to the United States. Today, Castle Hill is a state historic site and also designated as a National Historic Landmark. A fully accessible walkway leads visitors to the top of the hill and provides outstanding views of downtown Sitka and waterfront. Interpretive panels provide opportunities to learn more about the history of this site.
