Yosef Karo

“ There are those who say that, similarly, if one sees the person for whom a miracle was performed, he should bless just as he would at the place where the miracle was performed.
סעיף ו על נס של רבו צריך לברך כשם שהוא מברך על נס של אביו. הגה: י"א דה"ה אם רואה האדם שנעשה לו הנס מברך עליו, כמו שמברך על המקום שנעשה בו הנס (אבודרהם) .
218:7 On a miracle of a notable person, such as Yoav son of Tzeruya and his like, and on a miracle of a person by whom the Heavenly Name was sanctified, such as Daniel and his fellows, one makes a blessing. ”

“ Blessings that are made on miracles
ברכות הנעשים על הנסים
218:1 Someone who sees a place where miracles were done for Israel, such as: the crossing of the sea, the crossing of the Jordan, the crossing of the Rivulets of Arnon, the stones of Elgavish of Beit Choron, the stone which Og wanted to throw on Israel, the stone that Moshe sat on during the war of Amalek, and the walls of Jericho, should bless as follows: "she'asah nissim la'avoteinu bamakom hazeh" - "who wrought miracles for our forefathers at this place." ”
