Citadelle du St-Esprit

Built by Vauban, the brilliant French military engineer, in the 17th century on the site of a former monastery, the Citadelle has typically wedge-shape fortifications. The "prow" affords wraparound views of the three spires of the cathedral, the curve of the Alzette, and the glass towers of the Kirchberg plateau beyond.
