The clock at the Florence Cathedral, also known as the Duomo, is a fascinating piece of engineering and art. Located on the inside of the cathedral's facade, the clock is an intricate timekeeping device that has been in operation for centuries.

One of the most remarkable features of the clock is its size. The main clock face measures over 6 meters in diameter, making it one of the largest clocks in the world. The face is adorned with beautiful decorative elements, including intricate golden hands that point to the hours and minutes.

The clock mechanism itself is a marvel of engineering. It is powered by a system of weights and gears, which are carefully calibrated to ensure accurate timekeeping. The movement of the gears is visible through a small window on the clock face, allowing visitors to witness the inner workings of the clock.

One notable aspect of the clock is its inclusion of both Roman and Arabic numerals. The Roman numerals are used for the hour markers, while the Arabic numerals indicate the minutes. This combination of numeral systems adds a unique touch to the clock's design.

As for the history of the clock, it was installed in the Florence Cathedral in the late 14th century. Over the years, it has undergone several renovations and improvements to maintain its functionality and aesthetic appeal.
