One of the house walls on Plac Zamkowy bears a plaque devoted to the most famous inhabitant of Szeroka Street as Yaakov Yitzchak Horovitz (1745-1815), a Hasidic rabbi known as the Seer of Lublin (Castle Square 10).His house of prayer, founded in 1794, was located in the yard of the house between 28 Szeroka Street and Nadstawna Street, that is at the place where a statue of a lion now stands, a symbol of Lublin’s ties with the Ukrainian city of Lviv.The Seer of Lublin was a disciple of Dov Ber of Mezritch and Elimelech of Lizhensk, and a teacher of many Hasidic tzadiks, such as the founders of the Kotzk and Peshischa dynasties. Many events from his life, including the mysterious circumstances of his death, are shrouded by hagiographic legend, described, among others, by Martin Buber in his Gog and Magog and Tales of the Hasidim.Professor Władysław Panas, the author of the essay The Eye of the Tzadik, noticed that Plac Zamkowy has the shape of an eye, and the Seer of Lublin’s synagogue was located where the pupil would be. And when seen from above, Plac Zamkowy, along with the rectangular shape of the castle, create a symbolic matzevah.Yehuda Leib Eiger (1816-1888), the founder of the Lublin Eiger Hasidic Dynasty, also prayed in the house of prayer at 28 Szeroka Street. The synagogue of his son Abraham (1847-1914) and grandson Shlomo Eiger (1871-1940) was located a few houses further, at 40 Szeroka Street. Golda and Kaja Finkler, Abraham Eiger’s granddaughter and great-granddaughter, both Holocaust survivors, described their childhood at the court of the Hasidic rabbi in Lives Lived and Lost: East European History Before, During, and After World War II as Experienced by an Anthropologist and Her Mother (Brighton, 2012).
