The Villa Mairea is an estate that includes a large house and a guest house. It was designed by famous architect Alvar Aalto and built in 1939. It was a unique project for Alvar because he was employed by a wealthy couple, Harry and Maire Gullichsen, and was allowed to experiment with his ideas. They told Alvar that he should design it as if it were an experimental house. Today, the Villa Mairea is considered the best work of Alvar Aalto.
