I thought it quite strange that a museum would be called Central Bank until I got there. It appears that the bank owns the land and/or finances it's operation as the museum is in an adjoining building to the Banco Centro. Before Ecuador was conquered by the Inca there were other cultures there. Cuenca was the city of the Cañari people. We saw Cañari on the bus coming from Riobamba. They were attractive people but like many of the other indigenous groups they were quite small and wore little light colored bowler hats. Anyway, the location of the Museo Banco Centro was a royal Cañari palace which after being conquered by the Inca became a royal Inca palace naturally. It seems the city was founded (which they called Guapondeleg) about 500 AD which makes it very old for an American city. The Incas took over in about 1450 or so. The Inca replaced the Cañari architecture with their own impressive works and in some of the buildings you can see the layers. The Cañari didn't have the advanced carved stone architecture that the Incas had but it was no worse than what the Spanish eventually built over top the Inca buildings.
