The Torre de Reloj, or clocktower, is the principle entrance into the old walled city. The tower itself dates to the 19th century. On the plaza, there are often roving vendors, though it is primarily is a stopping point for the horse drawn carriages. On one side, under a row of colonial archways, is the Portal de Los Dulces, where maybe a dozen vendors have set up sidewalk stands selling lots of sugary snacks, most involving coconut.
