The Tiferet Yisrael Synagogue (Hebrew: בית הכנסת תפארת ישראל; Ashkenazi Hebrew: Tiferes Yisroel), most often spelled Tiferet Israel, also known as the Nisan Bak Shul (Yiddish: ניסן ב"ק שול), after its co-founder, Nisan Bak[1] is a former prominent Hasidic Jewish congregation and synagogue, located in the Jewish Quarter of the Old City of Jerusalem, Israel.

The synagogue was inaugurated in 1872 by the Ruzhin Hasidim among the members of the Old Yishuv[citation needed] and was destroyed by the Jordanian Arab Legion on 21 May 1948 during the Battle for Jerusalem of the 1948 Arab–Israeli War.

He informed him that Czar Nikolai I intended to buy a plot of land near the Western Wall with the intention of building a church and monastery there.

Bak managed to buy the land from its Arab owners for an exorbitant sum mere days before the Czar ordered the Russian counsul in Jerusalem to make the purchase for him.

[11] A study by architect Faina Milstein concludes that it is likely that Eppinger either fully designed, or at least advised Nisan Bak on the construction of the synagogue.

The Kaiser smiled and replied, "I hope the roof will be built soon", and left the Austrian counsel with 1,000 French francs[13] for the dome's construction.

The first major Haganah stronghold to fall was the Nissan Bek Synagogue, the building whose dome had been donated by the Emperor Franz Joseph.

It was essential to Rusnack defence plan and the Haganah fought tenaciously to hold on to it…Fawzi el Kutub finally ordered eight of his men to rush across an open space and place a charge at the base of the synagogue.

Like a spider he pressed himself up against its wall until finally the Tunisian to whom he had promised a wife rushed out to him carrying a fifty-five pound charge.

Three more unsuccessful attempts were required before Kutub managed to blow a hole in the synagogue wall and a party of Legionnaires rushed through the smoke into Nissan Bek's interior.

Sure that the Haganah would counterattack and that the irregulars swarming into the synagogue would quickly turn to looting, Kutub decided to destroy it with a 220-pound charge.

As the smoke cleared and the frightful devastation caused by the bomb became apparent, Kutub heard a cry of consternation rising from the Jewish posts around him.

A small group of Haganah led by Judith Jaharan counterattacked and took the smoking ruins of Nissan Bek from the Arabs.

The Haganah found the bodies of Arab irregulars killed in their counterattack with altar cloths around their waist, pages of the Torah stuffed into their shirts, pieces of chandeliers and lamps in their pockets.
