Soo Hotel
The Soo Hotel was later known as the Princess Hotel, The Patterson Hotel Annex, The Hotel Dakotan, Heritage Recovery Center, and Heritage Apartments. It is a historic building located on Fifth Street North in Bismarck, North Dakota, United States, and was listed on the National Register of Historic Places in 1983. It was built by prominent businessman and political powerhouse Edward Patterson in 1906 as a second-class hotel to his other property, the high-class Northwestern Hotel. The four-floor, 76-room hotel was named after the Soo Line Railroad which had arrived in town in 1902 and whose depot was located several blocks away. It was briefly the tallest building in Bismarck. History Edward Patterson chose Fargo architect Milton Earle Beebe to design the hotel. Beebe had previously designed the Patterson Block for him, also listed on the National Register and located around the corner from the Soo on Main Street. The basement and first two floors were constructed of reinforced concrete with the upper walls being tied to concrete facing blocks pressed at the construction site. The third and fourth floors were constructed entirely of six-inch cement blocks with wood framing due to the fourth floor possibly being a last-minute addition.
