Torre dell'Orologio, Renaissance clock tower in Piazza della Loggia, Brescia, Italy.

Torre dell'Orologio is a 16th-century clock tower on Piazza della Loggia, built in stacked tiers above a dark gray wall. Its main dial, framed by a white stone arch with Roman numerals, has concentric rings of blue, gold and dark markings and two golden winged heads at the upper corners. Above it sit a white panel with a faint circular carving, a curved pediment with a weathered painted panel of figures, and at the top two dark metal figures flanking a central bell.

The tower was built between 1540 and 1550 to a design by Brescian architect Lodovico Beretta, who also worked on the adjacent Palazzo della Loggia. Its astronomical clock, made by Paolo Gennari da Rezzato between 1544 and 1546, replaced a 15th-century clock on another side of the square that was retired in 1543. The main dial was painted by Gian Giacomo Lamberti in 1547, and the copper automata were added with the bell in 1581.

The two copper figures beside the bell, driven by the clock mechanism, strike the hours; in Brescian dialect they are called "Màcc de le ure", the madmen of the hours, nicknamed Tone and Batista after the French Revolution. The main dial, painted by Gian Giacomo Lamberti in 1547, shows the Moon's phase and age and the Sun's place in the zodiac, read in the 16th century for astrological guidance.

The tower stands on the west side of Piazza della Loggia, and the passage Lodovico Beretta built at its base in 1554 leads through to Via Beccaria and Piazza Paolo VI. The astronomical dial faces the square; a second, simpler dial showing only the hour overlooks Via Beccaria at the back. The automata strike the hours and repeat the chimes about two minutes later.

The clock mechanism was calibrated before the Gregorian calendar reform, so it marks the spring equinox on March 11 instead of March 21. This quirk reflects how the tower preserves a moment in history when astronomical knowledge was still evolving.
