Maastricht, the Netherlands. Detail of the Westwork arches spanning the street Sint Servaasklooster and the Westwork of the Basilica of Saint Servatius. The narrow gate in the centre and the support stones at the bottom (above the arch) indicate the position of the covered walkway that was once attached to this wall, enabling the provost to reach the church from his home accross the street without being seen. Photograph taken from the monastery of the Sisters of Mercy of St. Borromeo (<i>Zusters Onder de Bogen</i>).
