(the Tremont Street Shul) in Cambridge, Massachusetts (opened 1925 as Temple Ashkenaz), and the Beth Efraim Bukharian Jewish Synagogue in Forest Hills, New York (70th Avenue). Some of these American examples are modeled after specific European synagogues, others are best classified as vernacular architecture. A Canadian example is the Beth Jacob Synagogue in North York, Ontario. Balconies with curtains or one-way glass More strict congregations add a curtain to the balcony so that men cannot see even women's faces. Central partition A fixed-height gate or planter running down the center of the room, so that women and men both face front side by side. Often these partitions are minimal height (3 feet). In addition to the partition, sometimes the women's section is elevated by about a foot above the men's section. Example of a lower partition with a raised floor is in Anshe Shalom Bnei Israel synagogue in Chicago and Young Israel of Ocean Parkway in Flatbush, Brooklyn. An example of a medium-high partition () without a raised floor is the Adas Israel in Hamilton, Ontario. An example of a higher partition with a raised floor is in Mount Sinai Jewish Center of Washington Heights in Manhattan. Booth Synagogues that expect very few women to attend provide a token space that can accommodate about six women comfortably. The space is demarcated by moveable, opaque partitions that are over high. Examples are in the Yeshiva University beit midrash, and the Shabbat afternoon service at Young Israel of Avenue J in Flatbush, Brooklyn. In some synagogues, the booth is a supplement to the balcony, to accommodate women who have difficulty walking up the stairs (such as at She'erith Israel Congregation, Glen Avenue, Baltimore). Fixed-height opaque wall Sometimes with a non-opaque curtain, screen, glass, or other material above the wall, which can include: blinds or a curtain that can be opened during announcements or a sermon, etched glass, stained glass, a one-way screen with lights so that women can see through without being seen (e.g. Beth Jacob Shaarei Zion and Suburban Orthodox in Baltimore). The mechitza at the Bostoner Rebbe's synagogue in Brookline, Massachusetts, is made entirely of panels from the Boston John Hancock Tower (which had been removed from that building due to safety concerns). The Bostoner Rebbe chose these panels because they are one-way glass so the women can see out, but men cannot see into the women's section. Later, the
