English: 19th-century drawing by amateur artist and historian Philippe van Gulpen in a first floor corridor in the cloisters of the Kruisherenklooster in Maastricht, the Netherlands. The Gothic Monastery of the Crutched Friars dates from the 15th century and was converted into a luxury hotel, the Kruisherenhotel, in 2003-05. The drawings and water colours by Van Gulpen on display here were collected by the hotel owner Camille Oostwegel. This drawing is a copy of a drawing by the Bollandist Daniel Papaebroich published in the Acta Sanctorum in 1688. It depicts a led plaque discovered in 1666 in the small crypte of the Church of St Servatius in Maastricht. The plaque was seen as the ultimate proof for the burial of Charles of France, duke of Lower Lorraine and pretender to the crown of France, at this location in 1001.
