Located at the foot of the Palatine Hill, Santa Maria Antiqua is the oldest and most significant Christian monument in the Roman Forum. The church was abandoned in the 9th century after an earthquake buried the buildings; it remained sealed for over 1000 years until its rediscovery in the early 20th century. Therefore, Santa Maria Antiqua represents a key element for the understanding of the cultural and urban development of the Roman Forum from Antiquity into the first centuries of the Christian period. Following a conservation program, the church is now open for tours.
The church contains a unique collection of wall paintings from the 6th to late 8th century. The discovery of these paintings have given many theories on the development of early medieval art and given distinctive beliefs in archaeology. The church has the earliest Roman depiction of Santa Maria Regina, the Virgin Mary as a Queen, from the 6th century.
References:The Chapel of St. Martin is the only completely preserved Romanesque building in Vyšehrad and one of the oldest in Prague. In was built around 1100 in the eastern part of the fortified outer ward. Between 1100 and 1300, the Rotrunda was surrounded by a cemetery. The building survived the Hussite Wars and was used as the municipal prison of the Town of the Vyšehrad Hill.
During the Thirty Years’ War, it was used as gunpowder storage, from 1700 to 1750, it was renovated and reconsecrated. In 1784, the chapel was closed passed to the military management which kept using it as a warehouseand a cannon-amunition manufacturing facility. In 1841, it was meant to be demolished to give way to the construction of a new road through Vyšehrad. Eventually, only the original western entrance was walled up and replaced with a new one in the sountren side. The dilapidating Rotunda subsequently served as a shelter for the poor.
