A Roman garrison offering spectacular views over the plains and Bergamo’s Alpine foothills, it was rebuilt in the twelfth century and referred to as the Chapel, after the little church dedicated to St. Mary Magdalene contained inside. Subjected to modifications and expansions beginning in the fourteenth century, in the 1500’s it was merged with the Fort of San Marco with an embankment where a covered road ran. Today it is the site of a public park.
