The palace where the Shah used to live, in the northern part of the city, is surrounded by a big relaxing park. Nowadays it is a museum and is furnished as to reproduce how it was with the Shah. All rooms are very well dispayed and, of course, objects in them are luxurious and beautiful.
To my European eyes the museum seemed quite a celebration of the happy Shah times, especially compared to the hard times Iranians are living these days. But why should the current regime show the richness and refinement of the so detested Shah family? That is the question I asked to the local friends who were accompanying us.
The answer is that the museum has a very different idelogical purpose. The Islamic regime wants to show Iranians how rich the Shah family was compared to normal people. The museum is to blame luxury, not to celebrate it, and to mark a (supposed) difference with the current regime.
