San Sisto Vecchio

On the left-hand corner is San Sisto Vecchio, founded in the 5th century, but its interior was completely altered by Innocent III (1198-1216) and his successor Honorius III (1216-1227).
Restored under Benedict XIII (1394-1409 and 1417) by Filippo Ragazzini, who left only the Romanesque campanile unchanged.
Campanile from the time of Innocent (beginning of the 13th century).

Details: the campanile has three storeys of equal height showing triforiums with stone columns.
Between the storeys and below the roof, cornices with double saw-tooth friezes enclosing consoles; double-jointed decorative arches over the openings, and embossed bands with saw-tooth friezes projecting from the corners of the arches; traces of holes that probably contained bacini.
Because of the high, undecorated wall surfaces above the arches, and its extreme regularity, this campanile may appear somewhat monotonous. This was possibly caused by a restoration during 1930-1935.
