Always on the lookout for interesting museums to visit, as well as affordable sightseeing options and ways of entertaining the boy, we decided a visit to the CosmoCaixa of Barcelona was in order. The CosmoCaixa is Barcelona’s Science Museum. Originally built in the early 20th century as an asylum for the blind, it was expanded and reopened as the Barcelona Science Museum in the early 1980’s. In 1998, it underwent six years of redesign, reconstruction and expansion to open under its new name and under the guidance of the Spanish social foundation “la Caixa”.
