At the top of the staircase is the landing leading to the Hall of the Great and General Council and to the Hall of the Council of the XII.

Between the two doors of the Hall of the Great and General Council is the ceramic triptych, originally decorating the clock tower, realised in 1894 by the Roman ceramist Guglielmo Castellani on the drawing of San Marino artist Pietro Tonnini.

Because of the severe damage caused by environmental agents during the short period in which it adorned the façade of the Building, this triptych was removed from its place in 1922 and substituted with an identical one in mosaic, commissioned to a Murano specialised firm.

According to tradition, this work depicts Saints Leo, Marino and Agata, but its correct interpretation is called in question by the unusual clothing of Marino, dressed as a Roman soldier. More plausible seems a recent hypothesis, according to which the saint in the middle is Saint Quirino, designated as protector of the Republic in 1547.                                                                                                                              

This hypothesis also seems confirmed by the fact that Saint Marino is nevertheless depicted on the façade of the Building in the beautiful bronze statue moulded by Giulio Tadolini.
