The Trenčín Synagogue is one of the most remarkable works in Slovakia from the beginning of the 20th century. However, synagogues can be found in many other cities and states.

Synagogues are diverse and their architecture often reflects the specifics of a given part of the world. You would not find two identical Jewish temples in Slovakia either. But what unites them?
