I have noticed in many examples of traditional Ashkenazi schul architecture that there are two towers flanking the entrance.
Examples may be seen in such disparate locations as Gąbin, Poland (Gombin), Frankfurt (IRG–Khal 'Adath Jeschurun), Chelsea, MA (Walnut St. Schul–Agudas Sholom), and Budapest (Dohányi St. neolog schul).
Some non-Ashkenazi schuls, such as the Great Synagogue of Florence (Italki) also exhibit this feature.
This prompts three questions:
- Is this architectural practice referred to at all in rabbinic literature, or sourced therefrom?
- Is there any significance to the towers outside of rabbinic literature?
- Should this feature be kept in newer schuls?
