In the 16th century, a rabbi made note of the remains of an ancient synagogue in the village of Baram in the upper Galilee, not far from the Israel-Lebanon border. The structure still stands, and it sheds much light on how Jews prayed in talmudic times. Ron Traub writes:
There are essentially three types of ancient synagogues: the first built during the mishnaic period (70-200 CE), the second in the 3rd and 4th centuries CE, and the last group from the latter part of the Byzantine period (324-638 CE). Baram . . . is purported to be one of the 24 synagogues built by Rabbi Simon bar Yoḥai, who lived in the 2nd century CE. However [most] archaeologists . . . maintain that the synagogue was built at least a century later.
The [structure] measures 15.2 by 20 meters. The southern façade, which faces Jerusalem, has three openings. External to the southern façade are eight columns that run parallel to the building front. The columns supported an overhead pediment not found in other synagogues of the period.
The space between the columns and the façade is known as a vestibule, which is essentially a covered lobby next to the outer doors of the building. The internal plan has three longitudinal divisions that are defined by columns and include two narrow side aisles on either side of a wider central aisle known as a nave. An internal row of columns runs parallel to the back wall. The space between the columns and the back wall is known as an ambulatory and allows people to walk around the inside of the building without disturbing the congregants in the center. . . .
An inscription under the right window of the southern façade reads “Elazar bar Yudan built it.” An unusual feature is the presence of a three-dimensional sculpture: a pair of stone lions featuring a winged Victory and images of animals.
