The building itself looks like a space ship from the other planet. It opens rather late: at 11.00. There are several museums inside. We spent about 4 hours visiting different exhibitions. One feels hungry but there is no food in the museum cafe. They serve only tea/coffee.
The car museum is big and full of interesting car models. Some of them quite old. People are allowed to take photos there, but if you approach the car a lot the security panicks.))
There is an exhibition of miniatures of famous buildings in Baku. It's also worth visiting. There is also etnography and archeology exhibition there.
But my favorite museum there is toys museum! It's the best toys museum I've ever seen. The dolls look like sculptures not like dolls. They look like real human beings but of small size. Some of the dolls represent local people in national clothes. They must be heroes from local legends and fairy tales. Their clothes is so rich in details! The other dolls represent Kings, princes or Queens from middle ages. They all look like real art. There is a section with funny dolls.
