War of the Pacific

During the War of the Pacific, the temple was one of the places where the Peruvian troops hid the flag of the "2nd Line" Regiment of the Chilean Army's Infantry, captured during the battle of Tarapacá by Mariano Santos Mateo. This was recovered in 1880 by Chile.

The same year, after the battle of Tacna, the remains of the Peruvian soldiers were laid to rest in the temple.

Flag procession

During the administration of Tacna by Chile, in 1901, during the National Holidays of Peru on July 28, a procession of the Peruvian flag with a gold border left from the temple, being the first procession of the city's flag. With this restriction, the "Sociedad de Auxilios Mutuos El Porvenir" of Tacna asks the mayor of Tacna, Salvador Vergara Álvarez, to give it permission to hold a blessing ceremony for the institution's new flag.

The demonstration was authorized (after having originally rejected it due to the existing prohibition of displaying Peruvian patriotic symbols) by the Chilean interim mayor of the province of Tacna, General Salvador Vergara Álvarez, with the condition that it had to be done in silence (something that was fulfilled by the Peruvians), "without any manifestation of a patriotic nature" so as not to provoke clashes between Chileans and Peruvians caused by cheers in favor of Peru.^[2]

With permission, on July 28, 1901, it was carried out. Upon arrival, the flag was carried through uncrowded streets of the city^[6] to later be blessed in the church by the parish priest Alejandro Manrique, who blessed the flag by reciting the prayer "The Cross and the Flag" (Spanish: La Cruz y la Bandera). After the mass, the members of the society transport the flag in a procession from the temple, continuing along Unanue Street, to their location in Alto Lima. The Peruvian population of Tacna and Arica accompanied it in silence through the streets of Tacna. Finally, at the society's premises, the poet Federico Barreto recited a poem to the flag. From that date on, this would be the only public celebration of the Peruvian national holidays in the provinces of Tacna and Arica. After being taken through the central streets of the city, it arrived at the premises of the Benemérita Sociedad de Artesanos y Auxilios Mutuos El Porvenir.^[2]

Closure and destruction

On November 24, 1909, the church was closed by Mayor Máximo Lira [es] due to the activities of the church's priests who promoted pro-Peruvian sentiment. The guards continued blocking the entrance uninterruptedly, changing sentinels every 12 hours for approximately one year.^[6] The priests also still depended on the archdiocese of Arequipa. On March 3, 1910, Mayor Lira decreed the expulsion of the Peruvian priests within 48 hours. On March 5, with permission from the authority, Mariano Indacochea Zeballos, the church's priest from Arequipa, celebrated the last Peruvian mass in the church at 6:30 a.m. The mayor's office extended the deadline to 48 more hours when the priests were finally expelled from the city^[6] and the temple was subsequently destroyed.

Recovery attempts and current status

In 2014, the Decentralized Directorate of Culture tried to recover and value the site before the Regional Government of Tacna.

The land is owned by the Charity of Tacna, it was vacated in 1994, and in 2013 it was returned to administration.^[2] The Charity, lacking a budget, asked the regional government to prepare a project to request funds from the Peruvian national government for the recovery of the land. This was proposed to the Ministry of Culture but due to the lack of studies it could not be carried out.^[3]

In 2017 the Directorate of Culture intervened since the site was converted into a parking lot by the Charity.^[4]
