An elevation sight amount for a piece of artillery includes a support to accommodate a goniometer and two perpendicular spirit levels to check the verticality of the goniometer. The support is rotatably mounted around an axis oriented perpendicular to a longitudinal axis of the barrel of the piece of artillery, to a lever part. The support 1 is rotated using a first control button. The lever part is fastened in a hinged manner to a fixed element that is integral with the barrel so that the lever part can rotate about an axis oriented substantially parallel to the longitudinal axis of the barrel. In addition, a connecting rod is hinged to the lever part and the fixed element. The connecting rod 9 works with a second control button to enable the lever part to be rotated.
