Yep.
As Rabbi Daniel Dalin says: “During the Nazi occupation of Rome, three thousand Jews found refuge at one time at the pope’s summer residence at Castel Gandolfo. Amazingly, Castel Gandolfo is never mentioned or discussed in the anti-papal writings of many of the pope’s critics. Yet at no other site in Nazi-occupied Europe were as many Jews saved and sheltered for as long a period as at Castel Gandolfo during the Nazi occupation of Rome. Kosher food was provided for the Jews hidden there, where, as George Weigel has noted, Jewish children were born in the private apartments of Pius XII, which became a temporary obstetrical ward.”
“Pius’s critics who do mention Castel Gandolfo argue — ludicrously — that the Jews were sheltered at the pope’s summer residence without direct papal knowledge or involvement. But the fact is that Castel Gandolfo is under the official jurisdiction of the pope and no one but he has the authority to open its doors. According to several eyewitnesses, including Monsignor Carroll-Abbing, that is precisely what Pius XII did.”
