I visited the Judenhof in Speyer in autumn 2020, when the ShUM cities were still part of the Tentative List. I found it very impressive and it actually fascinated me more than Speyer Cathedral, which is right next door and which I was actually there for.
On a trip through western Germany in May 2024, I also visited the Heiliger Sand cemetery in Worms. I was extremely impressed by it and have even upgraded my already positive rating on this website. The cemetery is very small, after half an hour you have seen everything (unless you are able to read the Hebrew writing on the gravestones...). The cemetery is the oldest Jewish cemetery preserved in situ in Europe with graves dating back to the 11th century. The grounds are also very beautiful with old trees and flowers.
Important information: The cemetery can now be visited during normal opening hours without a tour, except on Saturdays and on Jewish holidays. There is no entrance fee, but male visitors must wear a head covering! The Cathedral of Worms is only a 5 minute walk away and is also worth a visit.
