A majority of the population is Roman Catholic, as well as other Christian denominations. As a result, Dominican churches play an important role in the culture and history of the country, dating back to the days of the Spanish colonialists. Tour the most significant church in the Colonial City: the Catedral Primada de América, the oldest in the Americas, where official national celebrations take place. The Colonial City is filled with many more breathtaking, important religious sites you can reach on foot, such as Iglesia Nuestra Señora de Las Mercedes, one of two representations of the country’s patron saint. Dominicans make a pilgrimage to Higüey every January 21, to the Basílica Catedral Nuestra Señora de La Altagracia, the country’s most important shrine dedicated to the DR’s patron saint, the Virgin Mary, and often included on tours from Punta Cana. Off the beaten track, a visit of the Holy Hill of Santo Cerro and adjoining church is worthwhile to see the third holiest site in the DR, just outside of La Vega, where Dominicans make a pilgrimage on September 24, Day of the Señora de Las Mercedes.
