Lal-lo, in the province of Cagayan, holds a quiet but significant place in Philippine history as the former Nueva Segovia, once the center of Spanish colonial administration and ecclesiastical authority in northern Luzon. Walking through the town today, there is little of the former grandeur that marked it as a colonial capital, yet its legacy remains embedded in one enduring structure, the Saint Dominic de Guzman Parish Church, more commonly known as Lal-lo Church.
