As a border

edit

The border between Ghana and what was then French Upper Volta (now Burkina Faso) was fixed by treaty between the French and British at the Conference of Paris in 1898, to be the 11th parallel.[3] The border does not follow the boundary exactly, but follows it approximately, crossing over it several times.
