Jeff Davis County was founded in 1887 and it was named in honor of Jefferson Davis, who was the President of the Confederate States of America. Jeff Davis county has a unique shape (a pentagon with no equal sides and no north and south boundaries) and is the only county in the United states that touches borders with another country at a single point. Jeff Davies county is home to the McDonald Observatory which draws visitors and scholars from all around the country. The county itself is home to many tourist attractions such as the Fort Davis National Historic Site, Davis Mountains State Park, Mt. Livermore and many others.
