The Synagogue

How a synagogue works, from the ark that holds the Torah scrolls and the eternal light above it to the bimah where the Torah is read, all facing towards Jerusalem.

Part by part

Point at a number in the drawing or at a name in the list to see where each part is.

  1. Entrance and mezuzah

    A small case fixed to the right-hand doorpost holds a mezuzah, a parchment with verses from Deuteronomy, as on Jewish homes. Many synagogues have a lobby with a rack of prayer shawls and skullcaps, and today often a security check.

  2. Prayer hall

    The main room where the congregation prays, with benches or seats arranged around the bimah or facing the ark. A full communal service requires a minyan, a quorum of ten adults; in Orthodox practice these are ten men, while most other movements count women too.

  3. Women’s section

    In Orthodox synagogues men and women sit separately, the women in a gallery above or behind a partition called a mechitza. Reform, Conservative and Reconstructionist synagogues generally have mixed seating. Historians debate how old the separate section is, since ancient synagogues show little clear evidence of galleries.

  4. Bimah

    A raised platform with a reading desk, where the Torah scroll is unrolled and read aloud and where the service is often led. In traditional Ashkenazi synagogues it stands in the centre of the hall; in Sephardi synagogues it is often at the opposite end from the ark, and Reform synagogues usually move it to the front.

  5. Menorah

    The seven-branched lampstand of the ancient Temple is the oldest symbol of Judaism and often appears in synagogues as an emblem, in stained glass or as a lamp. Some authorities discourage making an exact copy of a Temple vessel, so synagogue lamps often have six or eight branches; the nine-branched lamp of Hanukkah is a different object.

  6. Wall facing Jerusalem

    Jews traditionally pray facing Jerusalem and the site of the Temple, so synagogues are built with the ark on the wall that faces it, which in Europe and the Americas is the eastern wall, called the mizrach, “east”. Seats along this wall were traditionally places of honour.

  7. Eternal light

    A lamp hanging in front of the ark that is never put out, called the ner tamid. It recalls the lamp that the Book of Exodus commands to burn continually in the sanctuary. Once fuelled by oil, it is now usually electric.

  8. Ark

    The aron ha-kodesh, “holy ark”, is a cabinet or niche set into the wall facing Jerusalem, often raised up a few steps and richly carved. A decorated curtain, the parokhet, hangs in front of it or inside its doors. It is opened at solemn moments of the service, and the congregation stands.

  9. Torah scrolls

    Inside the ark stand the Torah scrolls, the Five Books of Moses written by hand in Hebrew on parchment by a trained scribe. Ashkenazi scrolls are dressed in a velvet mantle with silver finials and a breastplate; Sephardi and Mizrahi communities often keep them in rigid cases. Readers follow the text with a pointer, the yad, so that the parchment is not touched.

In brief

  1. I.A synagogue is a Jewish house of prayer, study and assembly, known in Hebrew as beit knesset, “house of gathering”, and in Yiddish as shul.
  2. II.Its focus is the ark, a cabinet on the wall facing Jerusalem that holds the handwritten Torah scrolls, with an eternal light burning before it and a raised platform, the bimah, from which the Torah is read.
  3. III.Synagogues existed before the Romans destroyed the Temple in Jerusalem in 70 CE, but after its destruction they became the centre of Jewish religious life wherever Jews lived.
  4. IV.There is no single required style, and synagogues have been built in the local architecture of every land, from medieval Prague and Toledo to the Moorish Revival temples of nineteenth-century Europe.

Visiting respectfully

  • Men, and in many congregations all visitors, cover their heads; skullcaps are usually available at the entrance.
  • Dress modestly, and in Orthodox synagogues sit in the section for your gender.
  • On the Sabbath and festivals do not take photographs, use phones or write, as observant members refrain from these activities.
  • Stand when the congregation stands, for example when the ark is opened.
  • Expect security checks, and contact the synagogue in advance if you wish to visit.

What the records show

  • Inscriptions from Ptolemaic Egypt dating to the third century BCE mention Jewish prayer houses, the earliest evidence for synagogue-like institutions.
  • Remains of synagogues from before 70 CE have been found in the land of Israel, at sites such as Gamla, Masada and Magdala.
  • The synagogue of Dura-Europos in Syria, from the mid-third century CE, was decorated with wall paintings of biblical scenes, now in the National Museum of Damascus.
  • The Old New Synagogue in Prague, built around 1270, is usually described as the oldest active synagogue in Europe.

Common misconceptions

  • Synagogues are sometimes thought to be the Jewish equivalent of the Temple. Jewish tradition holds that there was only one Temple, in Jerusalem, and the synagogue replaced its sacrifices with prayer and study; that is why the menorah and the eternal light are memories of the Temple rather than Temple vessels.
  • It is often assumed that the rabbi is a priest who must lead every service. Any knowledgeable adult member, within the rules of the community, may lead prayers or read the Torah; the rabbi is a teacher and an authority on Jewish law.
  • Some believe Judaism has always forbidden all images in synagogues. Ancient synagogues such as Dura-Europos and Beth Alpha, with its zodiac mosaic, show that attitudes varied, though images of God were never made and later synagogues generally avoided human figures.

Chapter I

From prayer house to the heart of Jewish life

Nobody knows exactly when the first synagogue was built. A long-held theory traces the institution to the Babylonian exile of the sixth century BCE, when Jews far from the Temple in Jerusalem may have gathered to pray and read their scriptures. The earliest firm evidence comes from Egypt, where inscriptions of the third century BCE dedicate Jewish “prayer houses”, in Greek proseuche, to God in honour of the Ptolemaic kings. By the first century CE, synagogues stood in towns across the land of Israel and in Jewish communities around the Mediterranean.

While the Temple stood, it remained the only place where sacrifices could be offered, and synagogues served for prayer, reading and teaching the Torah, and community meetings. The New Testament and the historian Josephus both describe Jews gathering in synagogues on the Sabbath to hear the scriptures read and explained. Archaeologists have found buildings of this period at Gamla, Masada, Herodium and Magdala: simple halls with stepped benches along the walls facing a central space.

The Roman destruction of the Temple in 70 CE transformed the synagogue’s place in Judaism. The rabbis taught that prayer and study could take the place of sacrifice, and the synagogue became the focus of Jewish worship. Synagogues of late antiquity were often richly decorated, with mosaic floors showing the Temple menorah, the ark and sometimes the zodiac, as at Beth Alpha in Galilee. Over time the Torah shrine, once a portable chest, became a fixed ark set into the wall facing Jerusalem, giving the building the layout it still has.

In medieval Europe and the Islamic world, synagogue building was often restricted by law. Christian and Muslim rulers at various times forbade new synagogues, limited their height so that they would not rise above churches or mosques, or required them to be inconspicuous from the street. Many synagogues were therefore modest from outside, set back in courtyards, with the floor of the prayer hall sometimes lowered below street level to gain height inside. Some communities linked this to the verse of the Psalms, “Out of the depths I have called you, O Lord.” The interior, by contrast, could be richly furnished, with a carved ark, embroidered curtains and silver ornaments for the Torah. Only with the legal emancipation of Jews in much of Europe in the eighteenth and nineteenth centuries did large, freestanding synagogues on main streets become common.

Chapter II

Prayer, Torah and community

Jewish tradition sets three daily prayer services, in the morning, afternoon and evening, and a synagogue with an active community may hold all three. The most important gatherings are on the Sabbath, from Friday evening to Saturday night, and on festivals. The high point of the Sabbath morning service is the reading of the Torah. The ark is opened, a scroll is carried in procession through the congregation, who often touch it with the fringes of their prayer shawls or with a prayer book, and it is unrolled on the bimah and chanted aloud.

The Torah is read in sections so that the whole of the Five Books of Moses is completed in a yearly cycle, which ends and begins again on the festival of Simchat Torah, when the scrolls are carried around the synagogue with singing and dancing. The year also brings the solemn High Holy Days of Rosh Hashanah and Yom Kippur, when the ram’s horn, the shofar, is sounded and the synagogue is at its fullest, as well as Passover, Shavuot and Sukkot.

A synagogue is as much a community centre as a place of worship. The three traditional names express this: house of prayer, house of study and house of assembly. Many synagogues have a study hall with shelves of books, a school for children and rooms for celebrations. Life-cycle events take place there, above all the bar and bat mitzvah, when a young person first reads from the Torah, and often weddings. The rabbi is a teacher and guide rather than a priest, and the service is often led by a cantor or by members of the congregation.

Chapter III

Many lands, many styles

Because Jewish law sets few rules for the shape of a synagogue, Jewish communities usually built in the style of their neighbours. In medieval Prague, the Old New Synagogue of around 1270 has a Gothic vault. In Toledo, the building now known as Santa María la Blanca, built as a synagogue around the late twelfth or thirteenth century, has the horseshoe arches and white plaster of Spanish Islamic architecture; it became a church in the early fifteenth century, after the anti-Jewish violence of 1391 and the pressure that followed.

The Sephardi communities who settled in Amsterdam after leaving Spain and Portugal built the great Portuguese Synagogue, completed in 1675, with the bimah and ark at opposite ends of a long hall. Bevis Marks in London (1701), the oldest synagogue in Britain in continuous use, was modelled on it, and Sephardi congregations carried the tradition to the Americas, where the Touro Synagogue of 1763 in Newport, Rhode Island, is the oldest surviving synagogue building in the United States. In Poland and Lithuania, carpenters built wooden synagogues with tiered roofs and painted interiors; almost none survived the destruction of the Second World War.

In the nineteenth century, newly emancipated Jewish communities in Central Europe built large city synagogues, often in a Moorish Revival style meant to recall the Spanish golden age. The Dohány Street Synagogue in Budapest, completed in 1859, is the largest in Europe, and the Choral Temple in Bucharest, from the 1860s, is another example of the style. Modern synagogues range from such grand buildings to small rooms in apartment blocks, all still turned towards Jerusalem.

Questions people ask

What is the difference between a synagogue and a temple?

Traditionally the Temple was the single sanctuary in Jerusalem, destroyed in 70 CE. Many Reform congregations, starting in nineteenth-century Germany, chose to call their synagogues temples, while others use synagogue, shul or congregation.

Can non-Jews visit a synagogue?

Yes, most synagogues welcome respectful visitors, and many historic synagogues are open as museums. For security reasons it is usually best to arrange a visit in advance.

Why is the Torah read from a scroll rather than a book?

Jewish law requires that the Torah read in public worship be handwritten on parchment in the form of a scroll, following ancient practice. Printed books are used for following along and for other prayers.
