It is located in the corner formed by Calle 10 and 12 with Gómez Farías, in the old San Francisco district or "Campechuelo" in Campeche City.

Its construction goes back to 1737, although it didn't have the Tower of the Clock yet. It seams that this small square was destined, basically for commercial purposes since the time it was built, although some of its spaces also served as homes; café’s, taverns, billiards as well as stores where the leather was hardened and rope manufacturing stores, liquor, soda and cookie factories, and drugstores among other, settled down in that place.

The clock of the small square was brought to Campeche in 1861 in order to be settled in the main parish church of the city; nevertheless it wasn’t installed on that place but years later it was put in the frontispiece of the Municipal Palace and later on in 1916, it was transferred to the church of San Román. Later on, this clock was repaired, transferred and placed in a tower built specifically for it, in front of the of San Francisco Place, where it exists up to now.

The clock that is appreciated in the tower that divides this same corridor, dates of 1889, although it was not installed in that place but until September 28, 1930.

It consists on an architectural group known popularly as "Los Portales de San Francisco" (San Francisco’s Porches) settled around a small square paved with a fountain in the center. Its shape is an irregular square and you can access to it though five streets.

The edifice of the porches has two corridors which cross perpendicularly on their northeast corner. The corridor on the East side is formed by seven mid point arches held by columns with pilasters and simulated capitals.

The corridor on the West side, which is the longer one, has 16 mid point arches being the one in the center the broadest one, and it accesses to the Gómez Farías Street. Above this same arch, which is decorated with a contour like a gear defined by two feigned pilasters and their respective cornices, the Tower of the Clock uproots, and it is the most outstanding element in the group.

The tower is squared and it is formed by two bodies; the first one has a vain in an arch of half point form in each one of its sides and it finishes off with a mold, and above it a decoration is appreciated formed by a series of rectangular bars placed in vertical position and in relief as some kind of merlons.

The second body, also in a square shape only smaller than the first one, holds a clock of four faces; in its superior part there are groups of five perforations in form of arch on each side and it finishes off with a similar decoration to that of the first body. In one of the inferior arches of the tower it lodges a commemorative badge of the placement of the clock that indicates the year of 1930.

The superior part of the facade of both corridors presents a cornice with frieze decoration with designs of groups of two horizontal rectangles and clipped and concave corners. To the right of one of the corridors a Franciscan shield is observed worked in quarry stone and embedded in the wall. The roof of the corridors is formed by beams and wooden small beams that cross it in perpendicular form.
