Indeed Chris, the site was used a great deal for propaganda purposes. A whole new washroom facility was installed, including rows of fine new sinks, to mislead the Red Cross visitors. Had they tried to turn any of the taps, they would have learned that there was no water connected. Even the currency was for a long time thought by many to be part of the cover up. It wasn't until survivors spoke out later that people began to realise that a currency had been issued, and was used in the ghetto.
p.s. Great choice for your honeymoon by the way, Prague is a beautiful city.
