In 1464, Jacobus Wiltingh, pastor of Garrelsweer and vicar in Loppersum, bequeathed Apell, a settlement among his possessions in the area called Westerwolde, to the Order of the Holy Cross on the condition that a monastery be built there,[REF] on the remains of a thirteenth-century Premonstratensian monastery [REF].
The monastery was bequeathed a number of gifts, including a stained glass window in 1561 by Lieutenant Johan de Mepsche and his wife Agnes, depicting Moses and the tablets containing the Ten Commandments [REF].
