MADRID, Spain — Amazon on Wednesday opened its first pop-up store in Spain in an old building in one of Madrid's prime shopping districts styled as a house with everything for sale, from clothing to electronic goods.

Similar stores will open in Italy, Germany and Britain, an Amazon spokeswoman said. The European pop-up stores illustrate how the world's largest online retailer, famous for upending retail chains' business, is increasingly turning to physical stores to attract and keep customers.

Amazon opened a new store in New York in September that allows shoppers to buy items from its website with the help of a smartphone app.

The company bought Whole Foods Market in a $13.7 billion deal last year, from which it is now delivering fresh food to shoppers' homes in the United States.
