Tucked away in a courtyard across the street from the Frankendael Park, this imposing church is dedicated to the Martyrs of Gorcum – 19 Dutch Catholic clerics who were hanged by the Calvinists in the 16th century for refusing to abandon their beliefs in the sacrament and the pope as the head of the church. Designed by A.J. Kropholler (1881 - 1973), a follower of iconic architect H.P. Berlage, the massive brick church, monastery and school buildings were built between 1924 and 1928.
