(JTA) — Charles, Prince of Wales, visited in secret the grave of his grandmother on the Mount of Olives in eastern Jerusalem.

The prince was in Israel on Friday for the funeral of Shimon Peres. Charles’ paternal grandmother, Princess Alice of Battenberg, is interred in the Church of Mary Magdalene on the Mount of Olives. She died in 1969 in London and was transferred to a crypt in the church in 1988 in accordance with her wishes.

Charles visited the grave later on Friday. No media was present, but some photos were later posted on social media, Haaretz reported.
