Sant'Andrea della Valle
church dedicated to Saint Andrew in Rome
Sant'Andrea della Valle is a titular church and minor basilica in the rione of Sant'Eustachio of the city of Rome, Italy. The basilica is the seat of the general curia of the Theatines and is located on the Piazza Vidoni, at the intersection of Corso Vittorio Emanuele (facing facade) and Corso Rinascimento. It is one of the great 17th century preaching churches built by Counter-Reformation orders in the Centro Storico (the others being San Carlo ai Catinari of the Barnabites, The Gesù and Sant'Ignazio of the Jesuits, and the Chiesa Nuova of the Oratorians).
Overview
A church was initially planned when, in 1582, Donna Costanza Piccolomini d'Aragona, duchess of Amalfi and descendant of the family of Pope Pius II, bequeathed her palace and the adjacent church of San Sebastiano in central Rome to the Theatine order for construction of a new church. Since Amalfi's patron was Saint Andrew, the church was planned in his honor. Work initially started around 1590 under the designs of Giacomo della Porta and Pier Paolo Olivieri, and under the patronage of Cardinal Gesualdo. With the previous patron's death, direction of the church passed to Cardinal Alessandro Peretti di Montalto, nephew of Pope Sixtus V. Work restarted by 1608, financed by what was then an enormous endowment of over 150,000 gold scudi, and with a more grandiose plan designed mainly by Carlo Maderno. The interior of the church was completed by 1650, with some changes added by Francesco Grimaldi.
Dome
The fresco decoration of Sant'Andrea's dome was one of the largest commissions of its day. The work was disputed by two Carracci pupils, Giovanni Lanfranco and Domenichino.
This brief starts where responsible research should: with the source description of “Sant'Andrea della Valle” as church dedicated to Saint Andrew in Rome. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the places & architecture register because the source frames it as church dedicated to Saint Andrew in Rome. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Jul 30, 2026. The linked authority identifier is Q1631593. VIAF identifies the subject as 137537813. The Library of Congress control number is no2001080565. Authority coordinates are 41.896, 12.475. 4 of 5 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1582, 1590, 1608 and 1650.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
