6Santa Maria in Trastevere
Designed by architect Carlo Fontana, the construction of the Santa Maria in Trastevere was completed in 1143.
Located in Rome, the church’s basic floor plan and wall structure date back to the 340s.
The first sanctuary was built in 221 and 227 by Pope Callixtus I, and later completed by Pope Julius I.
Two churches still standing were built in 340 AD, and one is this amazing church.
As the name suggests, the church was built in honor of Mary, mother of Jesus.
