Hello, dear friend Marcos @marcosmilano71. San Nicolás de Bari Church captivates me with its interesting architecture. Of all the religious buildings you've showcased in your previous posts, this church has a distinctive architectural character. I think the main profile of its roofing system has contributed to its eye-catching design. It features 3 cascading trapezoids (pyramids) that have a symbolic significance, as you said, to the divine Trinity. The interior's stained glass windows with blue and green tints have a calming effect, truly important for the holy atmosphere intended inside. Such a marvelous masterpiece indeed. Have a blessed Holy Week ahead. Take care and best wishes! 😊
