the st. ambrogio basilica (c.1130) is a monumental italian building. the church was originally founded by saint ambrose and is an outstanding example of mature lombard romanesque architecture because of its dependence on the architecture of ancient rome.
the church of sant' ambrogio incorporates an early christian basilical plan and contains the earliest example of ribbed-groin roof vaulting.
although the building's east end dates from the mid-10th century, most of it dates from the late 11th and the early 12th centuries.
the features typical of the lombardy romanesque include the basilican plan without transept, the lack of a clerestory, towers outside the perimeter walls, brick construction, and a vaulted covering.
the atrium or forecourt and the church's outer court reflect adherence to early christian traditions.
