San Luis De La Paz, Gto. Thursday, February 9, 2012. The San Luis Rey Parish atrial arch, built in the late nineteenth century, is undoubtedly the most representative symbol of the city. When you are away and think of San Luis de la Paz, is perhaps the first image that you remember. It is due to the fact that for years it has been used as the emblem of the logos of the regional fair, and that along with the parish is the representation of the town most utilized in postcards and photographs on the internet.
