There seem to be at least a million websites but the phone number eludes me - sorry.
The Old-New Synagogue isn't part of the Jewish Museum and needs a separate entry payment.
1270 doesn't sound terribly new but it was originally known as the New Synagogue because it replaced an even older one.
It's still used but the guide told me that the users aren't part of the old Czech Jewish community but immigrants.
You can go in the main chamber, which was men only and see the women's peepholes from an adjacent room.
