Detail of the convent garden of the Sisters of Mercy of St. Charles Borromeo (<i>Zusters Onder de Bogen</i>) in the centre of Maastricht, the Netherlands. The garden contains a large section of the 13th-century First Medieval City Wall of Maastricht, here seen from the west. The gazebo on top of the wall belongs to the former canon's house at Sint Servaasklooster 22 and was probably built in the 19th century. In the background the church towers of St. Servatius and St. John.
