Mariana is a Roman site south of Biguglia, in the Haute-Corse département of the Corsica région of south-east France. It lies in the littoral area known as La Marana, near the present town of Lucciana. There are two old churches in the area — the Church of Santa Maria Assunta and San Parteo Church.
It was founded in 93 BC as a military colony. Saint Devota, patron saint of Corsica and Monaco, is said to have been martyred here in 303 AD.
