This is the Clark Hotel, first built as the Cox Building in 1901 it has functioned in many capacities. After housing various buisinesses, from 1912-1914 it served as the courthouse. By 1920 it was bought by Fred Clark and turned into the Clark Hotel, which it remained until the 1970s.
This bar has sat in the building since the early 1900s when one of the businesses this building housed was a saloon. Even though the citizens voted the county dry in 1918, Fred Clark chose to keep the bar when he built his hotel. It made for a great conversation piece. I was told by the lady at the museum (now the old Clark Hotel building houses the towns museum) the bar itself was built in England and shipped to Van Horn. I can't find any info to verify her story, but that just makes it all the more intriguing.
