Gleaming after a much-lauded 2007 renovation, the Iglesia de Nuestra Señora de la Soledad is a massive brick structure dating from 1779. Its picturesque cream-and-terra-cotta tower actually predates the rest of the structure and is an eye-catching landmark on the city skyline. Inside there are ornate baroque frescoes and the hallowed font where patriotic hero Ignacio Agramonte was baptized in 1841.
