Cripta di San Giovanni in Conca

Cripta di San Giovanni in Conca stands in Milan as the surviving crypt of a paleochristian basilica built during the late Roman Empire. Only the crypt and part of the apse remain. Semicircular arches and carved capitals show Milanese Romanesque workmanship beneath the vanished church. The original Basilica Evangeliorum honoured the Evangelists before its later dedication to Saint John the Apostle and Evangelist.

Built between the fifth and sixth centuries, the basilica underwent Romanesque reconstruction after destruction by Frederick Barbarossa in 1062. A thirteenth-century rebuilding added a bell tower and divided the interior into three naves. In the fourteenth century, the Visconti family incorporated the basilica into their manor as a private chapel. Urban development led to the basilica’s demolition between 1948 and 1952, leaving the crypt and part of the apse.

Fragments of ancient sarcophagi preserve traces of Milan’s Roman artistic heritage. Roman decorative elements carry motifs ranging from mythological scenes to courtly themes. Arches, capitals, sarcophagus fragments and carved ornament bring several eras together in one surviving underground space.
