Casona Tristán del Pozo, Colonial mansion in Arequipa, Peru

The Casona Tristán del Pozo is a Spanish-era Andean Baroque house on San Francisco Street, near Arequipa's Plaza de Armas. Its rectangular doorway is flanked by pilasters forming niches with Tuscan columns, and a curved open pediment above. The plan forms a double square ring around two courtyards; the first has cobblestone paving and rooms with thirteen window and door crowns bearing Latin abbreviations and monograms.

Domingo Carlos Tristán del Pozo and his wife Ana María Carazas bought the plot on San Francisco Street, where the Andrés de Rosas brothers' house stood, on 24 June 1736. Construction of their residence began in 1738. Later owners included José Joaquín Tristán, Bishop Manuel Abad Yllana and Pío de Tristán; BBVA Perú acquired the house in 1974.

The facade carries a five-branched shrub with cantuta flowers holding medallions of Joaquín, Ana, María and José around a central Jesus. The thirteen window and door crowns of the first courtyard bear the Latin invocation Sanctus Deus, Sanctus Fortis, Sanctus Immortalis, Miserere Nobis. The second courtyard's arcade served as the family dining room in the 18th century.

The building is now run by a bank as a museum and art gallery that is open to the public. Visitors should note that opening times apply on weekdays and may differ on weekends.

The thirteen window and door crowns in the first courtyard carry abbreviations of the Latin invocation Sanctus Deus, Sanctus Fortis, Sanctus Immortalis, miserere nobis, alongside the monograms of Ana, Joaquín, María, Jesús and José. The façade tympanum shows a five-branched shrub with cantuta flowers holding medallions.
