"LAL-LO" Lal-lo by pres_16

The area of Lallo was the first important Spanish settlement in the Cagayan Valley; it was visited as early as 1572 by Juan de Salcedo.

The cathedral, now a parish church, is difficult to date. Fray Rodrigo de Cardenas, bishop from 1653 to 1661, ordered a structure built, the extant parts of which may be the bell tower and the nave.

The church, bell tower and convento ruins are almost wholly of a brick. The facade is clearly old, but the other parts are difficult to date.

Bells in the campanario dated 1694, 1790 and 1793 are further witnesses to Lallo's antiquity.
