What is the name of the historic fort in Astoria, Oregon, and when was it first constructed?

Fort Astoria is a historic fort located in Astoria, Oregon. It was first constructed in 1811 by the Pacific Fur Company, a subsidiary of John Jacob Astor's American Fur Company. The fort was originally named Fort George in honor of King George III of England, but was later renamed Fort Astoria after Astor himself.

The fort was built as a trading post and was an important center of the fur trade in the Pacific Northwest. It was also the first permanent American settlement on the west coast of North America.

The original fort was made of wood and consisted of several buildings surrounded by a palisade. The fort was rebuilt several times over the years, with the last reconstruction taking place in the 1950s. Today, the site of Fort Astoria is a National Historic Landmark and is open to the public as a museum.
