The original building dates back to the ned of the XII century and it was connected by a covered bridge to the palace of the Capitano del Popolo, another council judiciary that was located in the close building that still preserves the name.

Extremely laudable tower, erected in 1216 and provided, in 1483, of a mechanical watch in place of a previous one ( the remains are preserved in the Civici Musei, the current watch is of the XIX century). The tower was decorated in 1544 by Lelio Orsi, with monochrome frescoes, today disappeared and of which only the drawings remain)
