As part of the Amsterdam Card the synagogue is free so coming back from the zoo and seeing the exterior we decided to go in. Admittedly not knowing anything about synagogue's and the particular Religious aspects and the different rooms outside for different practices this was really interesting.
The actual synagogue has a lovely peaceful and spacious quality to it and great for just sitting and enjoying a calm break from the city for a little bit. Was an unexpected addition to the day's plan and became a highlight and something a bit different. Would recommend.
