    Several recent results suggest the conjecture that all finite Tits geometries of type \(C_ 3\) with thick lines are either buildings or flat. The author proves that if \(\Gamma\) is a finite Tits geometry of type \(C_ n\) (n\(\geq 3)\) with thick lines and if all residues of \(\Gamma\) of type \(C_ 3\) are either buildings or flat, then either \(\Gamma\) is a building or \(n=3\) and is flat.
