Next to the Tower of St. John, approximately where the Largo and Fountain of St. John now stand, there once stood a small chapel where St. John was venerated. Misfortune struck, and one day, the small chapel was severely damaged by a fire, with only a few statues surviving. With the demolition of the Tower of St. John, the chapel's fate was sealed and it, too, was dismantled.
Construction of the Chapel of St. John began on April 9, 1863, at its current location, on the left bank of the Lima River, at the very end of Alameda de S. João. The building was completed in 1867 and blessed on June 16 of the same year. It has only one altar, but the richness of its carvings deserves to be highlighted and appreciated. The chapel is octagonal in shape and, according to Miguel Roque dos Reys Lemos, in his Municipal Annals of Ponte de Lima, was, and still is, an "elegant and beautiful" chapel. This same author states, "the materials used in all the masonry work were taken from the tower and original chapel of the same saint and from the adjacent small section of the wall that then stood at the mouth of Rua de S. João."
