John Jacob Astor Hotel: The John Jacob Astor Hotel, originally known as the Hotel Astoria, is a historic former hotel building located in Astoria, Oregon, United States, and listed on the National Register of Historic Places (NRHP).  It is one of the tallest buildings on the Oregon Coast and is a "prominent landmark" in Astoria.  Constructed in 1922–23, the hotel opened in 1924 and initially was the city's social and business hub, but soon was beset with a variety of problems, and struggled financially for years.  It was renamed the John Jacob Astor Hotel in 1951, but a decline in business continued, as did other problems.  The building was condemned by the city for safety violations in 1968 and sat vacant for several years until 1984, when work to renovate it and convert it for apartments began.  It reopened as an apartment building in 1986, with the lowermost two floors reserved for commercial use.  The building was listed on the NRHP in 1979.  The world's first cable television system was set up in 1948 using an antenna on the roof of the Hotel Astoria.

Marshfield High School (Coos Bay, Oregon): Marshfield High School is a public high school in Coos Bay, Oregon, United States.  Coos Bay is located on the southern Oregon coast.  The campus consists of four major buildings, including an Intermediate building which opened in 2000 that serves as a math and science building.  It also has a gymnasium that seats 3,000.  There is also a separate facility that houses the Drama program.  Marshfield High School started in 1908 after being bought from the International Order of Odd Fellows, who owned the cemetery the school is built around.  Construction of the first building later known as the East Branch was finished a year after the purchase and was soon followed by a small gym with a pool in 1915.  By 1938, the small building was becoming crowded so the decision was made to make another building.  With the help of architect Francis Marion Stokes of Portland Oregon, the Main Building (1940) and the West Gym (1939) were added to the campus.  In 1952, another gym was installed in the center of campus claiming the name Main Gym.  The Main Building was extended onto the North side in 1953, and the West side in 1962.  The old East Branch was becoming out dated with the tall pillars and peaked roof compared to the Art Deco style of the rest of the campus, so it was remodeled in 1958.  Just before the turn of the century, the school decided to instal another building at the North side.  The old East Branch was becoming old, but the town wanted to keep it around for sentimental value, until the plaster ceiling came toppling down onto a desk.  Once Pirate Hall was completed in January 2000, the East Branch was relieved of duty, and soon became the parking lot for the students.
