There have been Jews in Lisbon at least since the Middle Ages, but the community suffered a major blow in 1497, when an edict by King Manuel I ordered Jews either to convert to Christianity or to leave the country.
All synagogues of Lisbon were confiscated by the King and given to Christian religious orders.
For the Jews that converted to Catholicism, called New Christians (cristãos novos), the establishment of the Portuguese Inquisition in 1536 meant a permanent danger of being persecuted.
The situation for Judaism in Portugal changed at the beginning of the 19th century, when the Portuguese Inquisition was abolished and Sephardi Jews from Morocco and Gibraltar, mostly merchants, started to migrate to Lisbon and other parts of Portugal.
During the whole 19th century, the small Lisbon Jewish community had no formal synagogue and had to celebrate their religious rites in private houses.

The tentative construction of a Jewish synagogue occurred in the 19th century, but there were difficulties, namely those associated with its official recognition by Portuguese monarchists.
An official request to construct the synagogue occurred on 4 March 1897, which was sent to London and Lourenço Marques on 12 October.
A commission was established to study its construction, nominated by the Jewish community in Lisbon, represented by Leão Amezalak, Abrahão Anahory, Mark Seruya, Jacob Levy Azancot, Saul Cagi and Jaime Pinto.

On 23 August 1901, the license was signed to buy the land along Rua Alexandre Herculano.
In 1902, though, the lands were donated to the Israeli Committee in Lisbon, and a plan was elaborated by Miguel Ventura Terra (1866-1919), recommended by a commission headed by Joaquim Bensaúde.
The plan allowed an operating space that could allow 400 men and 200 women to celebrate their religious worship.
On 25 May the cornerstone was laid for the construction of the building by Abraham E. Levy.
The synagogue was inaugurated on 18 May 1904, after work by builders Pereira de Campos: it was the first synagogue to be built in Portugal, since the late 15th century.
On the same year, a painting was executed by Veloso Salgado.

In 1940 a commission was established to collect funds for the repair of the roof, which was reconstituted again in 1948.
A plan was elaborated by architect Carlos Ramos for the repair of the synagogue.
In May 1949, the synagogue was reopened, during a solemn ceremony with the presence of the Chief Rabbi of Paris, Jacob Kaplan.

In December 1995, the building was proposed for heritage classification.

A solemn ceremony marking the 100 years of its construction was celebrated in December 2004.
Portuguese President Jorge Sampaio and Israel's Sephardi Chief Rabbi Shlomo Amar were among the speakers.
