Santa Maria in Castello, Former Romanesque church in Marano, Cupra Marittima, Italy

Santa Maria in Castello is a Romanesque church in the medieval village of Marano, Cupra Marittima. Its southern wall on the public road keeps splayed single-light windows and a semi-Gothic portal with geometric terracotta decoration. Inside, three large polylobed arches rest on terracotta columns, and a fresco of the Virgin and Child with Saints Lucy and Catherine of Alexandria fills the lunette beneath the presbytery canopy.

The church was first mentioned in written records in 1227 when documents confirmed a chaplain served there. Later it temporarily served different functions while maintaining its religious role before major restoration work in the mid-twentieth century.

In 1254, the General Parliament of Marano gathered within the church walls to ratify a significant agreement with the city of Fermo.

The church is privately owned and closed for worship, so it cannot be visited as an active place of worship. It stands in the medieval village of Marano, within Cupra Marittima, and is reached on foot through the borgo's lanes. Access depends on the private owners and the adjoining villa.

During 1621-1625, the building temporarily assumed the functions of the Parish Church of San Basso while maintaining its distinct religious identity.
