The church was specifically built to accommodate the large influx of pilgrims arriving to venerate the relic of Christ's blood.
The relic is brought out for public procession through the streets of Mantua only once a year on Good Friday.
The facade incorporates a giant order of pilasters, a design choice inspired by the Arch of Trajan at Ancona.
Andrea Mantegna, the famous Renaissance painter, helped design his own funerary chapel inside the basilica.
The central vault of the nave was one of the largest constructed since antiquity at the time of its completion.
The structure served as a prototype for many subsequent Renaissance churches, including St. Peter's Basilica in the Vatican.
The interior contains frescoes and paintings by artists of the Mantuan school, including Correggio's school.
The Basilica di Sant'Andrea is a major Renaissance church in Mantua, commissioned by Ludovico III Gonzaga and designed by Leon Battista Alberti in 1472. It serves as a co-cathedral and is renowned for housing the relic of the 'Precious Blood' of Christ, kept in sacred vessels beneath the high altar. The church features a triumphal arch facade and a massive barrel-vaulted nave, which broke away from the traditional basilican floor plan. Its octagonal dome, completed by Filippo Juvarra in the 18th century, stands as a dominant feature of the Mantuan skyline. The interior houses the tomb of the early Renaissance painter Andrea Mantegna, located in the first chapel on the left. The building's proportions reflect Alberti's theories on harmonic resonance and classical Roman architecture. It is a key example of the transition from Gothic to Renaissance religious architecture in Northern Italy.
The central nave looking toward the high altar highlights the barrel vault and the dome's light.
Visit the crypt to view the reliquary vessels that hold the relic of the Precious Blood.
Look for the funerary chapel of Andrea Mantegna, which contains a bronze bust of the artist.
Ensure you walk to the center of the nave to appreciate the scale of the barrel vaulting.
Avoid visiting during Sunday morning mass services if you intend to explore the architectural details as a tourist.
Occasionally closed to tourists during private liturgical functions or major religious feast days.
Modest clothing covering shoulders and knees is required; maintain silence as it is an active place of worship.
