The 300-room Alexander Young Hotel was built in 1902 at a cost of $2 million (initially, it had just under 200 rooms.) The hotel was built by Alexander Young, who came to Hawaii from Blackburn, Scotland in 1865. Mr. Young invested in sugar plantations and eventually became president of the Waiakea Mill Co. He also bought the famous Moana Hotel in Waikiki and the original Royal Hawaiian Hotel (which was not in Waikiki, but instead at Hotel and Richards Streets near the Iolani Palace.)
Alexander Young became a citizen of the Kingdom of Hawaii and served in the House of Nobles between 1887-1892. He also served on an advisory council for the Provisional Government after the overthrow of the Kingdom.
The Young Hotel was used by the military in both World Wars. During WWI, the U.S. Army used the second floor. During WWII, the military occupied most of the hotel. In 1964, the hotel was converted to offices. In 1980, the building was listed on the National Register of Historic Places, which did nothing to protect it from demolition the following year. Too bad. While it may not have been a spectacular building, it was definitely an important part of Honolulu's history. Here's a drawing of the
