The Modica historic center appeared to me to be less cohesive - and therefore less evocative - than that of some nearby similar cities, such as Scicli and Ragusa Ibla. This is probably because the disastrous 1902 flood, inducing the coverage of the two "Pozzo dei Pruni" and "Janni Mauro" streams - crossing the city and joining downstream from it - strongly modified what observers considered an urban landscape among the most picturesque in Italy, and introduced an element of modernity (paved streets instead of streams and bridges, resulting in motor traffic increase) that isn't found to the same extent in the other two cities I have mentioned.
This feeling of mine naturally doesn't prevent that even in this historic center there are spots of excellence, such as the "Chiesa Madre" of San Giorgio (at the top of its scenic staircase), and other churches such as San Giovanni Evangelista, il Carmine, Santa Maria of Betlem, San Pietro, and plenty of palaces; and above all this doesn't prevent the whole of the ancient building from being appreciable, as it can be well enjoyed from some viewpoints (I experienced the "Belvedere Pizzo"). But the feeling of something "hybrid", "imperfect", in the center of Modica, was in any case unavoidable for me.
Yet from this historic center, as the seat of the counts of Modica (who ruled the area for a very long time, since 1200 until 1812), the policies explaining the distinctive features of the entire current province of Ragusa, compared to those of the rest of Sicily, originated.
Two elements emerge from the history of the Modica County: starting from the first half of the fifteenth century, with the Cabrera family, originally from Catalonia, land was assigned to the peasants by the contract called "emphyteusis" (such contract provides for the assignment of a long-term plot of land to farmers, which often results in de facto ownership); these grants created a middle class of peasant owners with an advance of at least two centuries compared to other areas of Sicily (and therefore they founded the prosperity of the province and, indirectly, the splendor of its cities). The other element to consider is the pre-eminence of Modica County - pre-eminence granted by a series of kings of Sicily - among the other fiefs of the island as regards its strong autonomy from royal power; which meant that in the early modern age Modica was considered the third most important city in Sicily, after Palermo and Messina.
Of course today the castle of the Modica Counts is in ruins; and also Modica in 1927 was supplanted by Ragusa as the capital city of a new province. But all this must not make us forget that the policies determining the wealth of the territory, and therefore indirectly what we know today as the splendid Baroque heritage of all south-eastern Sicily, have emanated from this historic center for centuries.
