In the centre of Piazza Missori there are the remains of the ancient basilica of San Giovanni in Conca, an illustrious testimony of Milanese history and art from the 5th to the 17th century, built in the area of a Roman residential district from which the remains of mosaic flooring preserved at the Archaeological Museum. Today only a part of the apse remains outside, inexplicably not overwhelmed by the demolition of the building in 1949 to allow the opening of Via Albricci: built in early Christian times, at the end of the thirteenth century the church became the mausoleum of the Visconti family. The ancient underground crypt, the only example of a Romanesque crypt existing in Milan, is still intact. It has an atmosphere of intense meditation and where you can also admire Roman and medieval finds.
