Immediately north of the Domtoren , find the row of paving stones that mark the extents of the nave and the position of the columns. Across the way is the Domkerk, the surviving chancel of the cathedral. Back outside, look for the horizontal metallic plates showing the extents of the Roman town.
Behind the church is the most charming component of this ecclesiastical troika: Kloosterhof, a monastic garden and peaceful refuge.
A new component of the Domkerk experience, DOMunder , lets you go underground and view the excavated foundations of the Roman fortress that stood here. To purchase tickets and sign up for tours go to the Dom Under outlet next to the VVV.
