There is a law that requires all Dominican flags need to have the national coat of arms in the center.
Without the support of the Catholic church, there would be no Dominican Republic. Its also hard to not notice the effect of religion in everything that lead to the creation of the country, which impacted everything afterwards including many people finding their spouse, moving to DR, possibility of retiring without going broke, etc in our day. Santo Domingo probably is the largest city in the Americas with the most religious symbols glaring above, including the Plaza de la Bandera which has the largest Christian cross on the ground (main reason why a part of it requires an underpass). Almost all these places were built by the Dominican government and had the religious symbols intentionally added. Even the National Theater looks like a Christian cross from satelite images.
