An impressive 16th-century church and convent, Santo Domingo is the final resting place of two important Peruvian saints, including the continent’s first black saint, San Martín de Porres, whose skull sits encased in glass alongside the remains of Santa Rosa de Lima to the right of the main altar. Walkways of exquisite Spanish tiles lead to a string of cinematic courtyards throughout the convent. It all sits in salmon-colored glory a block from Plaza de Armas.
