The main attraction at this church is the ossuary chapel. When you enter the church, head to the right and follow the short corridor down to the ossuary. The photos on the attraction page give you an idea of what it looks like. In addition to the bones, there's also a cool fresco on the domed ceiling. The regular part of the church is nice but small. You can easily walk over here from the Duomo, and it's quick to visit, so if you are interested it's easy to work into your tour of Milan.
