Walk through the old Jewish neighborhood of Amsterdam where magnificent synagogues, striking buildings and impressive memorials dominate the streetscape. At its heart, occupying less than half a square mile, is the Jewish Cultural Quarter with its landmark buildings. Here, you can travel back in time to the days of Amsterdam’s Golden Age by visiting the Portuguese Synagogue or find out all about Jewish culture and history in the Jewish Historical Museum, the Children’s Museum, the National Holocaust Memorial and the National Holocaust Museum. Gassan Diamonds, a family-owned company, is located in a formerly steam-driven diamond factory in the center of Amsterdam. Every year more than 400,000 tourists visit the historical diamond factory. During a guided tour, multilingual staff will explain the various stages of diamond polishing. Observe skilled craftsmen at work as they transform the most precious crystal known to man into dazzling ready-to-wear brilliants. After the tour, browse through the extensive jewelry and watch collection in the boutique. By presenting your Jewish Cultural Quarter combi ticket, you will be served a glass of Champagne during the tour and afterwards, receive a brilliant gift.
